I have a very similar question to this question, but I am still one step behind. I have only one version of Python 3 installed on my Windows 7 (sorry) 64-bit system.
I installed NumPy following this link - as suggested in the question. The installation went fine but when I execute
import numpy
I got the following error:
Import error: No module named numpy
You can simply use
pip install numpy
Or for python3, use
pip3 install numpy
Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy.
Or simply using pip:
python3 -m pip install numpy
Installing Numpy on Windows
Open Windows command prompt with administrator privileges (quick method: Press the Windows key. Type "cmd". Right-click on the
suggested "Command Prompt" and select "Run as Administrator)
Navigate to the Python installation directory's Scripts folder using the "cd" (change directory) command. e.g. "cd C:\Program Files (x86)\PythonXX\Scripts"
This might be: C:\Users\\AppData\Local\Programs\Python\PythonXX\Scripts or C:\Program Files (x86)\PythonXX\Scripts (where XX represents the Python version number), depending on where it was installed. It may be easier to find the folder using Windows explorer, and then paste or type the address from the Explorer address bar into the command prompt.
Enter the following command: "pip install numpy".
You should see something similar to the following text appear as the package is downloaded and installed.
Collecting numpy
Downloading numpy-1.13.3-2-cp27-none-win32.whl (6.7MB)

Installing collected packages: numpy
Successfully installed numpy-1.13.3
I think there are something wrong with the installation of numpy.
Here are my steps to solve this problem.
go to this website to download correct package: http://sourceforge.net/projects/numpy/files/
unzip the package
go to the document
use this command to install numpy: python setup.py install
I also had this problem (Import Error: No module named numpy) but in my case it was a problem with my PATH variables in Mac OS X. I had made an earlier edit to my .bash_profile file that caused the paths for my Anaconda installation (and others) to not be added properly.
Just adding this comment to the list here in case other people like me come to this page with the same error message and have the same problem as I had.
You can try:
py -3 -m pip install anyPackageName
In your case use:
py -3 -m pip install numpy
You should try to install numpy using one of those:
pip install numpy
pip2 install numpy
pip3 install numpy
For some reason in my case pip2 solved the problem
Faced with same issue
ImportError: No module named numpy
So, in our case (we are use PIP and python 2.7) the solution was SPLIT pip install commands :
From
RUN pip install numpy scipy pandas sklearn
TO
RUN pip install numpy scipy
RUN pip install pandas sklearn
Solution found here : https://github.com/pandas-dev/pandas/issues/25193, it's related latest update of pandas to v0.24.0
You installed the Numpy Version for Python 2.6 - so you can only use it with Python 2.6. You have to install Numpy for Python 3.x, e.g. that one: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-win32-superpack-python3.2.exe/download
For an overview of the different versions, see here: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/
I had this problem too after I installed Numpy. I solved it by just closing the Python interpreter and reopening. It may be something else to try if anyone else has this problem, perhaps it will save a few minutes!
I had numpy installed on the same environment both by pip and by conda, and simply removing and reinstalling either was not enough.
I had to reinstall both.
I don't know why it suddenly happened, but the solution was
pip uninstall numpy
conda uninstall numpy
uninstalling from conda also removed torch and torchvision.
then
conda install pytorch-cpu torchvision-cpu -c pytorch
and
pip install numpy
this resolved the issue for me.
For those using python 2.7, should try:
apt-get install -y python-numpy
Instead of pip install numpy
I too faced the above problem with phyton 3 while setting up python for machine learning.
I followed the below steps :-
Install python-2.7.13.msi
• set PATH=C:\Python27
• set PATH=C:\Python27\Scripts
Go to http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Downloaded:- -- numpy-1.13.1+mkl-cp27-cp27m-win32.whl
--scipy-0.18.0-cp27-cp27m-win32.whl
Installing numpy:
pip install numpy-1.13.1+mkl-cp27-cp27m-win32.whl
Installing scipy:
pip install scipy-0.18.0-cp27-cp27m-win32.whl
You can test the correctness using below cmds:-
>>> import numpy
>>> import scipy
>>> import sklearn
>>> numpy.version.version
'1.13.1'
>>> scipy.version.version
'0.19.1'
>>>
I'm not sure exactly why I was getting the error, but pip3 uninstall numpy then pip3 install numpy resolved the issue for me.
Those who are using xonsh, do xpip install numpy.
For installing NumPy via Anaconda(use below commands):
conda install -c conda-forge numpy
conda install -c conda-forge/label/broken numpy
import numpy as np
ImportError: No module named numpy
I got this even though I knew numpy was installed and unsuccessfully tried all the advice above. The fix for me was to remove the as np and directly refer to modules . (python 3.4.8 on Centos)
.
import numpy
DataTwo=numpy.stack((OutputListUnixTwo))...
For me, on windows 10, I had unknowingly installed multiple python versions (One from PyCharm IDE and another from Windows store). I uninstalled the one from windows Store and just to be thorough, uninstalled numpy pip uninstall numpy and then installed it again pip install numpy. It worked in the terminal in PyCharm and also in command prompt.
this is the problem of the numpy's version, please check out $CAFFE_ROOT/python/requirement.txt. Then exec: sudo apt-get install python-numpy>=x.x.x, this problem will be sloved.
I did everything from the answers here but nothing worked. So I deleted all the previous installations of numpy using the commands below.
sudo rm -rf /usr/lib/python3/dist-packages/numpy*
sudo rm -rf /usr/lib/python3.7/dist-packages/numpy*
sudo rm -rf /usr/lib/python2.7/dist-packages/numpy*
Then just install using pip3.
sudo pip3 install numpy
Run
conda update --all
PS recall calling python using either "python2" or "python3" (not merely "python").
solution for me - I installed numpy inside a virtual environment, but then running ipython was not inside virtual env:
(venv) ➜ which python
/Users/alon/code/google_photos_project/venv/bin/python
(venv) ➜ which ipython
/usr/bin/ipython
so I had to install ipython, and run ipython from the venv like this:
python -c 'import IPython; IPython.terminal.ipapp.launch_new_instance()'
I was trying to use NumPy in Intellij but was facing the same issue so, I figured out that NumPy also comes with pandas. So, I installed pandas with IntelliJ tip and later on was able to import NumPy. Might help someone someday!
As stated in other answers, this error may refer to using the wrong python version. In my case, my environment is Windows 10 + Cygwin. In my Windows environment variables, the PATH points to C:\Python38 which is correct, but when I run my command like this:
./my_script.py
I got the ImportError: No module named numpy because the version used in this case is Cygwin's own Python version even if PATH environment variable is correct.
All I needed was to run the script like this:
py my_script.py
And this way the problem was solved.
Try uninstalling and then reinstalling the Python extension for VSCode.
I tried many different solutions, but this "hard refresh" was the only one that worked for me.
I just had the same problem as well! It turns out the problem happens when you're installing Numpy to a version of python and trying to run the program using another python version. Probably the global version of Python your text editor opens by default is different from the one that you need for the version of numpy you are running.
So to start off, run:
which python
python --version
which pip
pip list
If you can find numpy on the list, its most likely the python version you are using is not compatible with the version of numpy installed. Try switching to a different version of Python in this case.
If numpy is not installed just pip install numpy or pip3 install numpy depending upon your version of python.
For whom installation target is Raspberry Pi, as here they suggest:
sudo apt-get install libatlas-base-dev
could be working.
On MacOs, if you are getting this error in Pycharm and you installed Python3 and NumPy through Homebrew, the python interpreter path is probably not pointing to the Python interpreter that is installed by Homebrew. In Pycharm, go to Preferences>Project: [Project Name]>Python Interpreter, and enter /opt/homebrew/bin/python3 for the path to python interpreter.
Since yesterday I've had this error when I try to import packages on anaconda :
ImportError: Missing required dependencies ['numpy']
I have tried un-installing Anaconda and Python, switching to Python 2.7 but nothing works it's still the same error, here is the code I get :
Any help is really appreciated thanks !
I had this same issue immediately after upgrading pandas to 0.19.2. I fixed it with the following install/uninstall sequence from the windows cmd line:
pip uninstall pandas -y
pip uninstall numpy -y
pip install pandas
pip install numpy
This also broke my matplotlib install so I uninstalled/installed that as well.
Very odd behavior for a seemingly routine upgrade.
What happens if you try to import numpy?
Have you tried'
pip install --upgrade numpy
pip install --upgrade pandas
I had to install this other package:
sudo apt-get install libatlas-base-dev
Seems like it is a dependency for numpy but the pip or apt-get don't install it automatically for whatever reason.
I had this problem with last version of numpy 1.16.x
Problem resolved with
python3 -m pip uninstall numpy
python3 -m pip install numpy==1.14.0
Did you install miniconda and pandas without dependencies?
Try installing numpy first with conda install numpy or pip install numpy.
If you're on Windows you can get pre-compiled versions of most libraries that require compilation from here.
On Windows 10 Anaconda3-5.3.0-Windows-x86_64 I had the Missing required dependencies ['numpy'] error when running scripts as so, %HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe pandas_script_foo.py.
In my case the error was caused by missing Anaconda package PATH definitions when running Anaconda python.exe in a windows cmd.exe session. The numpy package is not missing. It just can't be found on the PATH.
The Anaconda installation includes windows shortcuts that give examples of configuring the PATH per script run. See the shortcuts in the %HOMEPATH%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit) directory for examples.
See the %HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py script to see how Anaconda configures PATH.
Below is an example windows BAT file that calls cwp.py to setup PATH, and then run a python script. Its a copy of the commands the Anaconda jupyter-lab shortcut executes.
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3 ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\Scripts\jupyter-lab-script.py
If you need to execute python scripts on Anaconda with the conveniance of running a BAT file, the above BAT file example should do the trick.
The data manipulation capabilities of pandas are built on top of the numpy library. In a way, numpy is a dependency of the pandas library. If you want to use pandas, you have to make sure you also have numpy. When you install pandas using pip, it automatically installs numpy. If it doesn't, try the following
pip install -U numpy pandas
For conda
conda install numpy pandas
I also faced the same issue. It happened to me after I upgraded my numpy library.
It was resolved in my case by upgrading my pandas library as well after upgrading my numpy library using the below command:
pip install --upgrade pandas
Try:
sudo apt-get install libatlas-base-dev
It should work now.
Else, try uninstall and reinstall numpy and pandas.
I had the same issue. It was because I had multiple versions of numpy installed. Remove all versions by repeatedly using:
pip uninstall numpy
Then re-install it with the command:
pip install numpy
First, try to import numpy on it's own, like so:
import numpy as np
I got this message:
ImportError: Something is wrong with the numpy installation. While importing
we detected an older version of numpy in
['/home/michael/.local/lib/python3.6/site-packages/numpy']. One method of
fixing this is to repeatedly uninstall numpy until none is found, then
reinstall this version.
So do what it says, keep uninstalling numpy until there is none, and then reinstall.
This worked for me.
I had the same issue while using Microsoft Visual Code with Python 3.7.3 64-bit('base':conda)as my python interpreter. Before running any code type the following three commands:
C:/ProgramData/Anaconda3/Scripts/activate #activate conda Scripts directory
conda activate base #activate conda
& C:/ProgramData/Anaconda3/python.exe #to run python
I have same problem.
I have got two version of numpy 1.16.6 and 1.15.4, fresh installed pandas did not work correctly.
I fixed it by uninstalling all versions of numpy and pandas and install the last versions.
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.16.6:
Successfully uninstalled numpy-1.16.6
Uninstalling pandas-0.24.2:
Successfully uninstalled pandas-0.24.2
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.15.4:
Successfully uninstalled numpy-1.15.4
Cannot uninstall requirement pandas, not installed
$ pip uninstall numpy pandas -y
Cannot uninstall requirement numpy, not installed
$ pip install numpy pandas
I had the same issue with anaconda package, it got updated.
anaconda {4.3.1 -> custom} ## I am not sure if this was the issue
Hit below command to know
conda list --revisions
what i did is just uninstall pandas with conda and re-install it
conda install pandas
Some new libs may also get installed with it.
It worked for me hope will do the same for you.
Uninstall all pip packages that you're having problems with. Manually remove all site-packages files. If you're using MacPorts, sudo port clean .
Then try reinstalling. Sometimes, there are files that should have been removed, but weren't if the installation was abruptly interrupted or something.
There could be an issue with conflicting versions of the package(s), as well as potentially issues with Pathing. Are you sure you've set the correct Path for your binaries? (/opt/local/bin, /anaconda2/bin, etc.)
Another issue could be some PYTHONPATH that's explicitly looking in the wrong place for the file.
I had a same issue recently with Anaconda with Python 3.7.
I solved this problem by downgrading python version to 3.6:
conda install python=3.6
and then by updating all the packages:
conda update --all
pandas is built on top of numpy so you need to have numpy to use the data manipulation feature, so install numpy first.
pip install numpy
This worked in my anaconda environment, but I do not know why conda does not work. For some reason conda uninstall was not sufficient. This only worked with conda remove.
conda remove pandas
conda remove numpy
conda install pip
pip install pandas
*With help from this answer
This raises the following import warning in python 3.6 and 3.7:
ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__
If you with to ignore this warning (and maybe other ImportWarnings), add the following to your script before importing pandas:
import warnings
warnings.filterwarnings('ignore', category=ImportWarning, module='_bootstrap.py')
In my case even though I was using the above options of uninstall and installing using pip the code was still giving me same errors.
Finally, I created a vritual environment and Installed numpy and pandas using pip in my virtual env. Now the code is running.
Steps: for Anaconda3 - Please change according to your installation type:
[if you dont have virtual env package installed]
$ pip install virtualenv
[from command prompt go to the directory by c:\anadonda3\scripts
[write the following command to use virtual env to create a virtual env for you in your desired location]
$virtualenv c:\anaconda3\envs\my_virtual_env
[once created you will have to activate your virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts activate
[now pip install numpy and pandas and other required packages using pip]
[once installations are done exit from the virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts deactivate
now use the python.exe inside your virtual env folder to run the script and it will run even with python 3.7.
I am using Win10 and Conda, and this issue just append to me when upgrading python 3.7.2-h8c8aaf0_0 --> 3.7.2-h8c8aaf0_2.
I solved it by return to the previous version with
conda install python=3.7.2=h8c8aaf0_0
If you're running your program on PyCharm on Windows, there is a known bug, because PyCharm simply doesn't add env-related paths to PATH.
The issue is fixed in the 2019.1 Early Access Preview (EAP) build.
For me installing the EAP fixed the issue.
nothing worked for me ... except when I found this
I suspect that you have a local file called unittest.py that is getting imported instead of the standard module.
I was trying to upgrade my anaconda 2 with anaconda 3. I tried installing Anaconda3-2018.12-Windows-x86 and Anaconda3-2019.03-Windows-x86_64 on my Windows 10 machine and failed with this error. For me, using Anaconda3-4.4.0-Windows-x86_64 for anaconda 3 worked the trick after trying everything listed in answers here.
I fixed this using Anaconda by going to Environments > base(root), searching for numpy in the installed modules and clicking the tickbox alongside it and choosing > Mark for specific version installation > 1.14.0 (as suggested by another user on this thread). Then clicking Apply. Once it downgraded numpy I stopped getting errors when running py files on the command line.
Throughout this saga, I was still able to use https://pypi.org/project/auto-py-to-exe/ even when I was getting the numpy errors on the command line, but it was a hassle to create an exe every time I wanted to test a change. It's all sorted now. I guess there was a problem with numpy 1.16.4.
Anyway, I hope this helps someone who's using Anaconda as well.
The following worked for me.
Deleted the folders for numpy and pandas together with their contents completely from the site-packages folder. Check depending on whether you are using python2 or python3. Check the exact path as per your machine.
N.B handle with care "rm -rf" command. If you are not sure of what you are doing, please do it manually using any file explorer of your choice!!
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/pandas*
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/numpy*
Then i installed clean packages for pandas and numpy as usual with
pip install numpy
pip install pandas
I've got the same error recently. Before applying uninstall or install tools, try to update your Jupyter.
How? Go to 'Environments' and type on the Search Packages box 'pandas'. Afterwards, check the version (if that column shows a blue number with a diagonal arrow, it means that your pandas is out of date). Click on 'pandas' and a option will pop up (choose 'Apply' and wait for a couple of minutes to update the package). And then, make a quick test on any notebook to make sure that your Jupyter is running smoothly.
For those who couldn't solve with the above answers:
Ensure that you are running python3 with
$ python version
If not, install python3.
Then change default python to python3 with
$ alias python=python3
Next, close your jupyter lab/notebook environment and re-launch it with default python being python3.
build_exe_options = {"packages": ["os",'pandas','numpy']}
It works.
you are running python 3.7
create environment for python 3.6
python3.6 filename.py
I want to import sklearn but there is no module apparently:
ModuleNotFoundError: No module named 'sklearn'
I am using Anaconda and Python 3.6.1; I have checked everywhere but still can't find answers.
When I use the command:
conda install scikit-learn should this not just work?
Where does anaconda install the package?
I was checking the frameworks in my python library and there was nothing about sklearn only numpy and scipy.
Please help, I am new to using python packages especially via anaconda.
You can just use pip for installing packages, even when you are using anaconda:
pip install -U scikit-learn scipy matplotlib
This should work for installing the package.
And for Python 3.x just use pip3:
pip3 install -U scikit-learn scipy matplotlib
Will leave below two options that may help one solve the problem:
Using conda
Using pip
One might want to consider the notes at the end, specially before resorting to the 2nd option.
Option 1
If one wants to install it in the root and one follows the requirements - (Python (>= 2.7 or >= 3.4), NumPy (>= 1.8.2), SciPy (>= 0.13.3).) - the following should solve the problem
conda install scikit-learn
Alternatively, as mentioned here, one can specify the channel as follows
conda install -c anaconda scikit-learn
Let's say that one is working in the environment with the name ML.
Then the following should solve one's problem:
conda install -n ML scikit-learn
# or
conda install -n ML -c anaconda scikit-learn
Option 2
If the above doesn't work, on Anaconda Prompt one can also use pip (here's how to pip install scikit-learn), so the following may help
pip install scikit-learn
However, consider the last note below before proceeding.
Notes:
When using Anaconda, one needs to be aware of the environment that one is working.
Then, in Anaconda Prompt, one needs to run the following
conda $command -n $ENVIRONMENT_NAME $IDE/package/module
$command - Command that one intends to use (consult documentation for general commands)
$ENVIRONMENT NAME - The name of one's environment (if one is working in the root,
conda $command $IDE/package/module is enough)
$IDE/package/module - The name of the IDE or package or module
If one needs to install/update packages, the logic is the same as mentioned in the introduction. If you need more information on Anaconda Packages, check the documentation.
What is the flag -c.
pip doesn't manage dependencies the same way conda does and can, potentially, damage one's installation.
If you are using Ubuntu 18.04 or higher with python3.xxx then try this command
$ sudo apt install python3-sklearn
then try your command. hope it will work
I did the following:
import sys
!{sys.executable} -m pip install sklearn
I've tried a lot of things but finally, including uninstall with the automated tools. So, I've uninstalled manually scikit-learn.
sudo rm -R /home/ubuntu/.local/lib/python3.6/site-packages/sklearn
sudo rm -R /home/ubuntu/.local/lib/python3.6/site-packages/scikit_learn-0.20.0-py3.6.egg-info
And re-install using pip
sudo pip3.6 install -U scikit-learn
Hope that can help someone else!
This happened to me, I tried all the possible solutions with no luck!
Finaly I realized that the problem was with Jupyter notebook environment, not with sklearn!
I solved the problem by re-installing Jupyter at the same environment as sklearn
the command is: conda install -c anaconda ipython. Done...
The other name of sklearn in anaconda is scikit-learn. simply open your anaconda navigator, go to the environments, select your environment, for example tensorflow or whatever you want to work with, search for scikit_learn in the list of uninstalled packages, apply it and then you can import sklearn in your jupyter.
SOLVED:
The above did not help. Then I simply installed sklearn from within Jypyter-lab, even though sklearn 0.0 shows in 'pip list':
!pip install sklearn
import sklearn
What I learned later is that pip installs, in my case, packages in a different folder than Jupyter. This can be seen by executing:
import sys
print(sys.path)
Once from within Jupyter_lab notebook, and once from the command line using 'py notebook.py'.
In my case Jupyter list of paths where subfolders of 'anaconda' whereas Python list where subfolders of c:\users[username]...
On Windows, I had python 3+ version. pip version - 22.3.1
I had installed:
pip install sklearn
But, it seems it is deprecated with scikit-learn.
So, I did:
pip install scikit-learn
And, it worked!!!
Cause
Conda and pip install scikit-learn under ~/anaconda3/envs/$ENV/lib/python3.7/site-packages, however Jupyter notebook looks for the package under ~/anaconda3/lib/python3.7/site-packages.
Therefore, even when the environment is specified to conda, it does not work.
conda install -n $ENV scikit-learn # Does not work
Solution
pip 3 install the package under ~/anaconda3/lib/python3.7/site-packages.
Verify
After pip3, in a Jupyter notebook.
import sklearn
sklearn.__file__
~/anaconda3/lib/python3.7/site-packages/sklearn/init.py'
I had the same problem.
The issue is when we work on multiple anaconda environments, not all packages are installed in all environments.
you can check your conda environment by writing the following code in anaconda prompt:
conda env list
then you can check the packages installed in each environment :
conda list -n NAME_OF_THE_ENVIRONMENT
for me, the environment that I was working with , was missing sklearn, although the package was installed in the other environments.
therefore, I just simply installed sklearn package in that particular environment
conda install -n NAME_OF_THE_ENVIRONMENT scikit-learn
and the issue was resolved
install these ==>> pip install -U scikit-learn scipy matplotlib
if still getting the same error then ,
make sure that your imoprted statment should be correct. i made the mistike while writing ensemble so ,(check spelling)
its
should be >>> from sklearn.ensemble import RandomForestClassifier
I had the same issue as the author, and ran into the issue with and without Anaconda and regardless of Python version. Everyone's environment is different, but after resolving it for myself I think that in some cases it may be due to having multiple version of Python installed. Each installed Python version has its own \Lib\site-packages\ folder which can contain a unique set of modules for that Python version, and where the IDE looks into folder path that doesn't have scikit-learn in it.
One way to try solve the issue: you might clear your system of all other Python versions and their cached/temp files/system variables, and then only have one version of Python installed anywhere. Then install the dependencies Numpy and Scipy, and finally Scikit-learn.
More detailed steps:
Uninstall all Python versions and their launchers (e.g. from Control Panel in Windows) except the one version you want to keep. Delete any old Python version folders in the Python directory --uninstalling doesn't remove all files.
Remove other Python versions from your OS' Environment Variables (both under the system and user variables sections)
Clear temporary files. For example, for Windows, delete all AppData Temp cache files (in C:\Users\YourUserName\AppData\Local\Temp). In addition, you could also do a Windows disk cleanup for other temporary files, and then reboot.
If your IDE supports it, create a new virtual environment in Settings, then set your only installed Python version as the interpreter.
In your IDE, install the dependencies Scipy and Numpy from the module list first, then install Scikit-Learn.
As some others have suggested, the key is making sure your environment is set up correctly where everything points to the correct library folder on your computer where the Sklearn package is located. There are a few ways this can be resolved. My approach was more drastic, but it turns out that I had a very messy Python setup on my system so I had to start fresh.
Using Anaconda-navigator UI environment
When running Anaconda-navigator:
Choose the 'Environments' tab on the left and create a new environment (e.g. ML - see Gonçalo Peres answer above, I made one called 'CourseraML').
Set Python version 3.7 (for Coursera course Applied Machine Learning in Python). Also include R.
Then find modules to install using the 'not installed' drop-down menu item. Search for each module needed in the search bar and select. sklearn is part of scikit-learn. Select it and install (it should find all relevant dependencies). Modules needed for Applied ML course: seaborn, numpy, scikit-learn, pandas, matplotlib
You'll need to restart Jupyter Notebook and reopen your file.
Command line version of above:
conda install -n CourseraML seaborn scikit-learn pandas numpy matplotlib graphviz
Causes
-your jupyter notebook might be importing the sklearn and other libraries from the
another the location(path) than the libraries from conda or pip.
MY Problem
In my case, My jupyter notebook was importing the libraries for snap manager. Since, I install jupyter using the snap instead of other ways.
You can check where other libraries are being imported in jupyter using code:
import cv2 as cv
print(cv.__file__)
Solution
So , I uninstall jupyter notebook and then install notebook using conda.
sudo snap remove jupyter
conda install -c conda-forge notebook
Since yesterday I've had this error when I try to import packages on anaconda :
ImportError: Missing required dependencies ['numpy']
I have tried un-installing Anaconda and Python, switching to Python 2.7 but nothing works it's still the same error, here is the code I get :

Try installing numpy first with conda install numpy or pip install numpy.
If you're on Windows you can get pre-compiled versions of most libraries that require compilation from here.
On Windows 10 Anaconda3-5.3.0-Windows-x86_64 I had the Missing required dependencies ['numpy'] error when running scripts as so, %HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe pandas_script_foo.py.
In my case the error was caused by missing Anaconda package PATH definitions when running Anaconda python.exe in a windows cmd.exe session. The numpy package is not missing. It just can't be found on the PATH.
The Anaconda installation includes windows shortcuts that give examples of configuring the PATH per script run. See the shortcuts in the %HOMEPATH%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit) directory for examples.
See the %HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py script to see how Anaconda configures PATH.
Below is an example windows BAT file that calls cwp.py to setup PATH, and then run a python script. Its a copy of the commands the Anaconda jupyter-lab shortcut executes.
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3 ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\Scripts\jupyter-lab-script.py
If you need to execute python scripts on Anaconda with the conveniance of running a BAT file, the above BAT file example should do the trick.
The data manipulation capabilities of pandas are built on top of the numpy library. In a way, numpy is a dependency of the pandas library. If you want to use pandas, you have to make sure you also have numpy. When you install pandas using pip, it automatically installs numpy. If it doesn't, try the following
pip install -U numpy pandas
For conda
conda install numpy pandas
I also faced the same issue. It happened to me after I upgraded my numpy library.
It was resolved in my case by upgrading my pandas library as well after upgrading my numpy library using the below command:
pip install --upgrade pandas
Try:
sudo apt-get install libatlas-base-dev
It should work now.
Else, try uninstall and reinstall numpy and pandas.
I had the same issue. It was because I had multiple versions of numpy installed. Remove all versions by repeatedly using:
pip uninstall numpy
Then re-install it with the command:
pip install numpy
First, try to import numpy on it's own, like so:
import numpy as np
I got this message:
ImportError: Something is wrong with the numpy installation. While importing
we detected an older version of numpy in
['/home/michael/.local/lib/python3.6/site-packages/numpy']. One method of
fixing this is to repeatedly uninstall numpy until none is found, then
reinstall this version.
So do what it says, keep uninstalling numpy until there is none, and then reinstall.
This worked for me.
I had the same issue while using Microsoft Visual Code with Python 3.7.3 64-bit('base':conda)as my python interpreter. Before running any code type the following three commands:
C:/ProgramData/Anaconda3/Scripts/activate #activate conda Scripts directory
conda activate base #activate conda
& C:/ProgramData/Anaconda3/python.exe #to run python
I have same problem.
I have got two version of numpy 1.16.6 and 1.15.4, fresh installed pandas did not work correctly.
I fixed it by uninstalling all versions of numpy and pandas and install the last versions.
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.16.6:
Successfully uninstalled numpy-1.16.6
Uninstalling pandas-0.24.2:
Successfully uninstalled pandas-0.24.2
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.15.4:
Successfully uninstalled numpy-1.15.4
Cannot uninstall requirement pandas, not installed
$ pip uninstall numpy pandas -y
Cannot uninstall requirement numpy, not installed
$ pip install numpy pandas
I had the same issue with anaconda package, it got updated.
anaconda {4.3.1 -> custom} ## I am not sure if this was the issue
Hit below command to know
conda list --revisions
what i did is just uninstall pandas with conda and re-install it
conda install pandas
Some new libs may also get installed with it.
It worked for me hope will do the same for you.
Uninstall all pip packages that you're having problems with. Manually remove all site-packages files. If you're using MacPorts, sudo port clean .
Then try reinstalling. Sometimes, there are files that should have been removed, but weren't if the installation was abruptly interrupted or something.
There could be an issue with conflicting versions of the package(s), as well as potentially issues with Pathing. Are you sure you've set the correct Path for your binaries? (/opt/local/bin, /anaconda2/bin, etc.)
Another issue could be some PYTHONPATH that's explicitly looking in the wrong place for the file.
I had a same issue recently with Anaconda with Python 3.7.
I solved this problem by downgrading python version to 3.6:
conda install python=3.6
and then by updating all the packages:
conda update --all
pandas is built on top of numpy so you need to have numpy to use the data manipulation feature, so install numpy first.
pip install numpy
This worked in my anaconda environment, but I do not know why conda does not work. For some reason conda uninstall was not sufficient. This only worked with conda remove.
conda remove pandas
conda remove numpy
conda install pip
pip install pandas
*With help from this answer
This raises the following import warning in python 3.6 and 3.7:
ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__
If you with to ignore this warning (and maybe other ImportWarnings), add the following to your script before importing pandas:
import warnings
warnings.filterwarnings('ignore', category=ImportWarning, module='_bootstrap.py')
In my case even though I was using the above options of uninstall and installing using pip the code was still giving me same errors.
Finally, I created a vritual environment and Installed numpy and pandas using pip in my virtual env. Now the code is running.
Steps: for Anaconda3 - Please change according to your installation type:
[if you dont have virtual env package installed]
$ pip install virtualenv
[from command prompt go to the directory by c:\anadonda3\scripts
[write the following command to use virtual env to create a virtual env for you in your desired location]
$virtualenv c:\anaconda3\envs\my_virtual_env
[once created you will have to activate your virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts activate
[now pip install numpy and pandas and other required packages using pip]
[once installations are done exit from the virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts deactivate
now use the python.exe inside your virtual env folder to run the script and it will run even with python 3.7.
I am using Win10 and Conda, and this issue just append to me when upgrading python 3.7.2-h8c8aaf0_0 --> 3.7.2-h8c8aaf0_2.
I solved it by return to the previous version with
conda install python=3.7.2=h8c8aaf0_0
If you're running your program on PyCharm on Windows, there is a known bug, because PyCharm simply doesn't add env-related paths to PATH.
The issue is fixed in the 2019.1 Early Access Preview (EAP) build.
For me installing the EAP fixed the issue.
nothing worked for me ... except when I found this
I suspect that you have a local file called unittest.py that is getting imported instead of the standard module.
I was trying to upgrade my anaconda 2 with anaconda 3. I tried installing Anaconda3-2018.12-Windows-x86 and Anaconda3-2019.03-Windows-x86_64 on my Windows 10 machine and failed with this error. For me, using Anaconda3-4.4.0-Windows-x86_64 for anaconda 3 worked the trick after trying everything listed in answers here.
I fixed this using Anaconda by going to Environments > base(root), searching for numpy in the installed modules and clicking the tickbox alongside it and choosing > Mark for specific version installation > 1.14.0 (as suggested by another user on this thread). Then clicking Apply. Once it downgraded numpy I stopped getting errors when running py files on the command line.
Throughout this saga, I was still able to use https://pypi.org/project/auto-py-to-exe/ even when I was getting the numpy errors on the command line, but it was a hassle to create an exe every time I wanted to test a change. It's all sorted now. I guess there was a problem with numpy 1.16.4.
Anyway, I hope this helps someone who's using Anaconda as well.
The following worked for me.
Deleted the folders for numpy and pandas together with their contents completely from the site-packages folder. Check depending on whether you are using python2 or python3. Check the exact path as per your machine.
N.B handle with care "rm -rf" command. If you are not sure of what you are doing, please do it manually using any file explorer of your choice!!
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/pandas*
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/numpy*
Then i installed clean packages for pandas and numpy as usual with
pip install numpy
pip install pandas
I've got the same error recently. Before applying uninstall or install tools, try to update your Jupyter.
How? Go to 'Environments' and type on the Search Packages box 'pandas'. Afterwards, check the version (if that column shows a blue number with a diagonal arrow, it means that your pandas is out of date). Click on 'pandas' and a option will pop up (choose 'Apply' and wait for a couple of minutes to update the package). And then, make a quick test on any notebook to make sure that your Jupyter is running smoothly.
For those who couldn't solve with the above answers:
Ensure that you are running python3 with
$ python version
If not, install python3.
Then change default python to python3 with
$ alias python=python3
Next, close your jupyter lab/notebook environment and re-launch it with default python being python3.
build_exe_options = {"packages": ["os",'pandas','numpy']}
It works.
you are running python 3.7
create environment for python 3.6
python3.6 filename.py
I have a very similar question to this question, but I am still one step behind. I have only one version of Python 3 installed on my Windows 7 (sorry) 64-bit system.
I installed NumPy following this link - as suggested in the question. The installation went fine but when I execute
import numpy
I got the following error:
Import error: No module named numpy
You can simply use
pip install numpy
Or for python3, use
pip3 install numpy
Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy.
Or simply using pip:
python3 -m pip install numpy
Installing Numpy on Windows
Open Windows command prompt with administrator privileges (quick method: Press the Windows key. Type "cmd". Right-click on the
suggested "Command Prompt" and select "Run as Administrator)
Navigate to the Python installation directory's Scripts folder using the "cd" (change directory) command. e.g. "cd C:\Program Files (x86)\PythonXX\Scripts"
This might be: C:\Users\\AppData\Local\Programs\Python\PythonXX\Scripts or C:\Program Files (x86)\PythonXX\Scripts (where XX represents the Python version number), depending on where it was installed. It may be easier to find the folder using Windows explorer, and then paste or type the address from the Explorer address bar into the command prompt.
Enter the following command: "pip install numpy".
You should see something similar to the following text appear as the package is downloaded and installed.
Collecting numpy

I think there are something wrong with the installation of numpy.
Here are my steps to solve this problem.
go to this website to download correct package: http://sourceforge.net/projects/numpy/files/
unzip the package
go to the document
use this command to install numpy: python setup.py install
I also had this problem (Import Error: No module named numpy) but in my case it was a problem with my PATH variables in Mac OS X. I had made an earlier edit to my .bash_profile file that caused the paths for my Anaconda installation (and others) to not be added properly.
Just adding this comment to the list here in case other people like me come to this page with the same error message and have the same problem as I had.
You can try:
py -3 -m pip install anyPackageName
In your case use:
py -3 -m pip install numpy
You should try to install numpy using one of those:
pip install numpy
pip2 install numpy
pip3 install numpy
For some reason in my case pip2 solved the problem
Faced with same issue
ImportError: No module named numpy
So, in our case (we are use PIP and python 2.7) the solution was SPLIT pip install commands :
From
RUN pip install numpy scipy pandas sklearn
TO
RUN pip install numpy scipy
RUN pip install pandas sklearn
Solution found here : https://github.com/pandas-dev/pandas/issues/25193, it's related latest update of pandas to v0.24.0
You installed the Numpy Version for Python 2.6 - so you can only use it with Python 2.6. You have to install Numpy for Python 3.x, e.g. that one: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-win32-superpack-python3.2.exe/download
For an overview of the different versions, see here: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/
I had this problem too after I installed Numpy. I solved it by just closing the Python interpreter and reopening. It may be something else to try if anyone else has this problem, perhaps it will save a few minutes!
I had numpy installed on the same environment both by pip and by conda, and simply removing and reinstalling either was not enough.
I had to reinstall both.
I don't know why it suddenly happened, but the solution was
pip uninstall numpy
conda uninstall numpy
uninstalling from conda also removed torch and torchvision.
then
conda install pytorch-cpu torchvision-cpu -c pytorch
and
pip install numpy
this resolved the issue for me.
For those using python 2.7, should try:
apt-get install -y python-numpy
Instead of pip install numpy
I too faced the above problem with phyton 3 while setting up python for machine learning.
I followed the below steps :-
Install python-2.7.13.msi
• set PATH=C:\Python27
• set PATH=C:\Python27\Scripts
Go to http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Downloaded:- -- numpy-1.13.1+mkl-cp27-cp27m-win32.whl
--scipy-0.18.0-cp27-cp27m-win32.whl
Installing numpy:
pip install numpy-1.13.1+mkl-cp27-cp27m-win32.whl
Installing scipy:
pip install scipy-0.18.0-cp27-cp27m-win32.whl
You can test the correctness using below cmds:-
>>> import numpy
>>> import scipy
>>> import sklearn
>>> numpy.version.version
'1.13.1'
>>> scipy.version.version
'0.19.1'
>>>
I'm not sure exactly why I was getting the error, but pip3 uninstall numpy then pip3 install numpy resolved the issue for me.
Those who are using xonsh, do xpip install numpy.
For installing NumPy via Anaconda(use below commands):
conda install -c conda-forge numpy
conda install -c conda-forge/label/broken numpy
import numpy as np
ImportError: No module named numpy
I got this even though I knew numpy was installed and unsuccessfully tried all the advice above. The fix for me was to remove the as np and directly refer to modules . (python 3.4.8 on Centos)
.
import numpy
DataTwo=numpy.stack((OutputListUnixTwo))...
For me, on windows 10, I had unknowingly installed multiple python versions (One from PyCharm IDE and another from Windows store). I uninstalled the one from windows Store and just to be thorough, uninstalled numpy pip uninstall numpy and then installed it again pip install numpy. It worked in the terminal in PyCharm and also in command prompt.
this is the problem of the numpy's version, please check out $CAFFE_ROOT/python/requirement.txt. Then exec: sudo apt-get install python-numpy>=x.x.x, this problem will be sloved.
I did everything from the answers here but nothing worked. So I deleted all the previous installations of numpy using the commands below.
sudo rm -rf /usr/lib/python3/dist-packages/numpy*
sudo rm -rf /usr/lib/python3.7/dist-packages/numpy*
sudo rm -rf /usr/lib/python2.7/dist-packages/numpy*
Then just install using pip3.
sudo pip3 install numpy
Run
conda update --all
PS recall calling python using either "python2" or "python3" (not merely "python").
solution for me - I installed numpy inside a virtual environment, but then running ipython was not inside virtual env:
(venv) ➜ which python
/Users/alon/code/google_photos_project/venv/bin/python
(venv) ➜ which ipython
/usr/bin/ipython
so I had to install ipython, and run ipython from the venv like this:
python -c 'import IPython; IPython.terminal.ipapp.launch_new_instance()'
I was trying to use NumPy in Intellij but was facing the same issue so, I figured out that NumPy also comes with pandas. So, I installed pandas with IntelliJ tip and later on was able to import NumPy. Might help someone someday!
As stated in other answers, this error may refer to using the wrong python version. In my case, my environment is Windows 10 + Cygwin. In my Windows environment variables, the PATH points to C:\Python38 which is correct, but when I run my command like this:
./my_script.py
I got the ImportError: No module named numpy because the version used in this case is Cygwin's own Python version even if PATH environment variable is correct.
All I needed was to run the script like this:
py my_script.py
And this way the problem was solved.
Try uninstalling and then reinstalling the Python extension for VSCode.
I tried many different solutions, but this "hard refresh" was the only one that worked for me.
I just had the same problem as well! It turns out the problem happens when you're installing Numpy to a version of python and trying to run the program using another python version. Probably the global version of Python your text editor opens by default is different from the one that you need for the version of numpy you are running.
So to start off, run:
which python
python --version
which pip
pip list
If you can find numpy on the list, its most likely the python version you are using is not compatible with the version of numpy installed. Try switching to a different version of Python in this case.
If numpy is not installed just pip install numpy or pip3 install numpy depending upon your version of python.
For whom installation target is Raspberry Pi, as here they suggest:
sudo apt-get install libatlas-base-dev
could be working.
On MacOs, if you are getting this error in Pycharm and you installed Python3 and NumPy through Homebrew, the python interpreter path is probably not pointing to the Python interpreter that is installed by Homebrew. In Pycharm, go to Preferences>Project: [Project Name]>Python Interpreter, and enter /opt/homebrew/bin/python3 for the path to python interpreter.
