So, I have been working in the jupyter lab and I have created a code that uses numpy.
In the jupyter I had no problem using numpy. I installed the library, and I used the command import to use such module.
However, I had to save my code as a py file. When I try to run my py file using my cmd, I receive this message:
ModuleNotFoundError: No module named 'numpy'
If i type in my cmd "pip show numpy" it shows me that I have numpy installed.
I also have tried to add to my code a line with:
pip install numpy
pip3 install numpy
python -m pip install numpy
python3 -m pip install numpy
conda install -c anaconda numpy
conda install numpy
and for every option I received a syntax error:
SyntaxError: invalid syntax
Can someone help me?
As mentioned in the comments section, it seems like your Python script (.py) was not using the correct environment. Please ensure that correct virtual environment is selected by doing conda activate name_of_the_kernel, where name_of_the_kernel should match the kernel used in your Jupyter notebook.
The requirements for the code to run is
Python 2.7
TensorFlow 1.n
SciPy & NumPy
I have python 2.7.8 by checking python --version. Installing them on python website also lead to a message saying there is no software to install so I assumed that I already have python 2.7x
For tensorflow I have install it using pip3 install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.0.0-py3-none-any.whl
and for Scipy and numpy i did brew install numpy scipy ipython jupyter
I have a python env setup call mypython.
Using pip list I have the following modules install as shown in the image.
But still VScode prompt an error and say that No module named 'tensorflow'when i run the code file.
How do I solve this?
enter image description here
Install Python extension instead of MagicPython;
You're using mypython in integrated Terminal but in left bottom corner, you select the global one,which is python3.10.1 as interpreter. Open Command Palette and choose Python: Select Interpreter, select mypython then reload window,the error should go away
Think you might be using the wrong pip. Could you run following in your terminal, with your venv activated.
$ pip --version
$ pip3 --version
Try installing with pip instead of pip3
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.

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 tried to install Numpy library with VisualStudio Code (VS Code) used the terminal and official website for instructions
Even though I followed each step I keep getting "This is the wrong setup.py file to run error"
I tried to update every element to not get an error, deleted and installed NumPy files in the directories which are in site-packages, and my anaconda files (i use jupyter as well but I need to implement this on my VSCode editor).
I also tried to get in the NumPy file and tried
pip install.
python setup.py build_ext --inplace
I used this site's instructions as well to install NumPy:
here I tried :
python -m pip install --user numpy
but keep getting the same error. What am I doing wrong?
In the screenshot you provided, I noticed that the installed module "numpy" exists in the "python3.7" folder, not in the "python3.8" you are currently using.
This is where my environment and numpy are located:
It is recommended that you use the shortcut key Ctrl+Shift+` to open a new terminal, VSCode will automatically enter the current environment, and then you can use "pip install numpy" to install numpy into "python3.8".
Or you can switch the environment directly to the python3.7 environment that includes numpy.
If it still doesn't work, you can uninstall numpy and reinstall it. ("pip uninstall numpy", "pip install numpy")
Since we are using pip to install the module numpy, we can use "pip --version" to check the currently used pip version, the module is installed in this environment:
