I have a very basic question. I want to install a new module on my computer in order to use it in Python (via Spyder). When I install the package via pip everything seems to work fine. When I want to import the package in my script it says that there is no module by that name (see scrennshot below)
Any suggestions what might be the problem?
Thanks a lot :)

You're using pip3 to install.
Try installing using pip install nibabel.
Failing that, I would refer you to the following question:
Which pip is with which python?
This is a common pitfall of using different versions of Python and pip.
I think
/Applications/Spyder.app/Contents/MacOS/python -m pip install nibabel
or
/Applications/Spyder.app/Contents/MacOS/python -m pip3 install nibabel
will solve your problem
Thanks for asking the question.
Have tried conda install
Since we are in anaconda dev env.
If you are using windows
Windows: Click Start, search, or select Anaconda Prompt from the menu
and use that terminal
please find the reference
https://docs.anaconda.com/anaconda/install/verify-install/
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)
100% |################################| 6.7MB 112kB/s
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.
I am a beginner in terms of using python. Currently, I got python 3.7 and I am using anaconda as IDE. For my project, I need to detect the location and brightness of points/dots in an external imported picture. I figure I could use the modul OpenCV. Unfortunately, I am stuck right now with the problem to import the module cv2. I already successfully installed the package using
python -m pip install OpenCV-python
on command prompt. OpenCV Version which was installed is 4.2.0.34. While compiling the test script of OpenCV on Spyder
import cv2
print(cv2.__version__)
I got this message
"ImportError : DLL load failed : The Modul was not found."
Can somebody let me know please how to fix this problem? Is somehow the version of OpenCV I got not compatible with the Python version? I already watched and followed many tutorial videos on Youtube, but I couldn't find the solution. I tried to copy the cv2.pyd to the site-packages folder in
C:/user/Anaconda3/Lib/site-packages directory
still it didn't fix the problem...
I would appreciate any answers and help I could get here. Thank you!
try installing it using these commands in the following order:
conda update anaconda-navigator
conda update navigator-updater
pip install opencv-python
It should work fine.
Try conda install opencv
or conda install -c menpo opencv
I've been using conda and jupyter notebook for a while now and recently I need some packages that are only available for install via pip. My understanding was that they are completely compatible and transparent with each other but apparently not.
I did a pip install pydicom and when I tried to do an import pydicom in my Jupyter Notebook, it says No module named pydicom.
In command prompt (using a Windows machine here) I ran conda list and I see pydicom is listed and marked as < pip >.
In my Jupyter notebook, this is my sys.executable output:
C:\Users\USERNAME\AppData\Local\Continuum\Anaconda2\python.exe
Is that normal/correct???
Disclaimer: I'm thoroughly confused by how the paths, environment, and dependencies work in conda and pip. I can't find a good tutorial or explanation how conda/pip work behind the scenes. Any pointers will be greatly appreciated!
While the package is named pydicom, you need to import dicom:
import dicom
You can also in install pydicom via conda. You need to provide the channel 'conda-forge`:
conda install -c conda-forge pydicom
You can find more packages a https://anaconda.org/. Just enter the package name in the search window. If the package is available you will see the channel you can with the -c option.
