ImportError#
In certain cases a failed installation or setup issue can cause you to
see the following error message:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE! Importing the numpy c-extensions failed. This error can happen for different reasons, often due to issues with your setup.
The error also has additional information to help you troubleshoot:
-
Your Python version
-
Your NumPy version
Please check both of these carefully to see if they are what you expect.
You may need to check your PATH or PYTHONPATH environment variables
(see Check Environment Variables below).
The following sections list commonly reported issues depending on your setup.
If you have an issue/solution that you think should appear please open a
NumPy issue so that it will be added.
There are a few commonly reported issues depending on your system/setup.
If none of the following tips help you, please be sure to note the following:
-
how you installed Python
-
how you installed NumPy
-
your operating system
-
whether or not you have multiple versions of Python installed
-
if you built from source, your compiler versions and ideally a build log
when investigating further and asking for support.
Using Python from conda (Anaconda)#
Please make sure that you have activated your conda environment.
See also the conda user-guide.
If you use an external editor/development environment it will have to be set
up correctly. See below for solutions for some common setups.
Using PyCharm with Anaconda/conda Python#
There are fairly common issues when using PyCharm together with Anaconda,
please see the PyCharm support
Using VSCode with Anaconda/conda Python (or environments)#
A commonly reported issue is related to the environment activation within
VSCode. Please see the VSCode support
for information on how to correctly set up VSCode with virtual environments
or conda.
Using Eclipse/PyDev with Anaconda/conda Python (or environments)#
Please see the
Anaconda Documentation
on how to properly configure Eclipse/PyDev to use Anaconda Python with specific
conda environments.
Raspberry Pi#
There are sometimes issues reported on Raspberry Pi setups when installing
using pip3 install (or pip install). These will typically mention:
libf77blas.so.3: cannot open shared object file: No such file or directory
The solution will be to either:
sudo apt-get install libatlas-base-dev
to install the missing libraries expected by the self-compiled NumPy
(ATLAS is a possible provider of linear algebra).
Alternatively use the NumPy provided by Raspbian. In which case run:
pip3 uninstall numpy # remove previously installed version apt install python3-numpy
Debug build on Windows#
Rather than building your project in DEBUG mode on windows, try
building in RELEASE mode with debug symbols and no optimization.
Full DEBUG mode on windows changes the names of the DLLs python
expects to find, so if you wish to truly work in DEBUG mode you will
need to recompile the entire stack of python modules you work with
including NumPy
All Setups#
Occasionally there may be simple issues with old or bad installations
of NumPy. In this case you may just try to uninstall and reinstall NumPy.
Make sure that NumPy is not found after uninstalling.
Development Setup#
If you are using a development setup, make sure to run git clean -xdf
to delete all files not under version control (be careful not to lose
any modifications you made, e.g. site.cfg).
In many cases files from old builds may lead to incorrect builds.
Check Environment Variables#
In general how to set and check your environment variables depends on
your system. If you can open a correct python shell, you can also run the
following in python:
import os print("PYTHONPATH:", os.environ.get('PYTHONPATH')) print("PATH:", os.environ.get('PATH'))
This may mainly help you if you are not running the python and/or NumPy
version you are expecting to run.
C-API incompatibility#
If you see an error like:
RuntimeError: module compiled against API version v1 but this version of numpy is v2
You may have:
-
A bad extension “wheel” (binary install) that should use
oldest-support-numpy (
with manual constraints if necessary) to build their binary packages. -
An environment issue messing with package versions.
-
Incompatible package versions somehow enforced manually.
-
An extension module compiled locally against a very recent version
followed by a NumPy downgrade. -
A compiled extension copied to a different computer with an
older NumPy version.
The best thing to do if you see this error is to contact
the maintainers of the package that is causing problem
so that they can solve the problem properly.
However, while you wait for a solution, a work around
that usually works is to upgrade the NumPy version:
pip install numpy --upgrade
Segfaults or crashes#
NumPy tries to use advanced CPU features (SIMD) to speed up operations. If you
are getting an “illegal instruction” error or a segfault, one cause could be
that the environment claims it can support one or more of these features but
actually cannot. This can happen inside a docker image or a VM (qemu, VMWare,
…)
You can use the output of np.show_runtime() to show which SIMD features are
detected. For instance:
>>> np.show_runtime() WARNING: `threadpoolctl` not found in system! Install it by `pip install \ threadpoolctl`. Once installed, try `np.show_runtime` again for more detailed build information [{'simd_extensions': {'baseline': ['SSE', 'SSE2', 'SSE3'], 'found': ['SSSE3', 'SSE41', 'POPCNT', 'SSE42', 'AVX', 'F16C', 'FMA3', 'AVX2'], 'not_found': ['AVX512F', 'AVX512CD', 'AVX512_KNL', 'AVX512_KNM', 'AVX512_SKX', 'AVX512_CLX', 'AVX512_CNL', 'AVX512_ICL']}}]
In this case, it shows AVX2 and FMA3 under the found section, so you can
try disabling them by setting NPY_DISABLE_CPU_FEATURES="AVX2,FMA3" in your
environment before running python (for cmd.exe on windows):
>SET NPY_DISABLE_CPU_FEATURES="AVX2,FMA3" >python <myprogram.py>
By installing threadpoolctl np.show_runtime() will show additional information:
... {'architecture': 'Zen', 'filepath': '/tmp/venv3/lib/python3.9/site-packages/numpy.libs/libopenblas64_p-r0-15028c96.3.21.so', 'internal_api': 'openblas', 'num_threads': 24, 'prefix': 'libopenblas', 'threading_layer': 'pthreads', 'user_api': 'blas', 'version': '0.3.21'}]
If you use the wheel from PyPI, it contains code from the OpenBLAS project to
speed up matrix operations. This code too can try to use SIMD instructions. It
has a different mechanism for choosing which to use, based on a CPU
architecture, You can override this architecture by setting
OPENBLAS_CORETYPE: a minimal value for x86_64 is
OPENBLAS_CORETYPE=Haswell. This too needs to be set before running your
python (this time for posix):
$ OPENBLAS_CORETYPE=Haswell python <myprogram.py>

Одна распространенная ошибка, с которой вы можете столкнуться при использовании Python:
Import error: no module named ' numpy '
Эта ошибка возникает, когда Python не обнаруживает библиотеку NumPy в вашей текущей среде.
В этом руководстве представлены точные шаги, которые вы можете использовать для устранения этой ошибки.
Шаг 1: pip установить numpy
Поскольку NumPy не устанавливается автоматически вместе с Python, вам нужно будет установить его самостоятельно. Самый простой способ сделать это — использовать pip , менеджер пакетов для Python.
Вы можете запустить следующую команду pip для установки NumPy:
pip install numpy
Для python 3 вы можете использовать:
pip3 install numpy
В большинстве случаев это исправит ошибку.
Шаг 2: Установите пип
Если вы все еще получаете сообщение об ошибке, вам может потребоваться установить pip. Используйте эти шаги , чтобы сделать это.
Вы также можете использовать эти шаги для обновления pip до последней версии, чтобы убедиться, что он работает.
Затем вы можете запустить ту же команду pip, что и раньше, чтобы установить NumPy:
pip install numpy
На этом этапе ошибка должна быть устранена.
Шаг 3: проверьте версию NumPy
После успешной установки NumPy вы можете использовать следующую команду для отображения версии NumPy в вашей среде:
pip show numpy
Name: numpy
Version: 1.20.3

Hi @seberg and @ksunden
Run the code with no cache dir param but no success, on the first moment, looks good but the same error. Also, I already have the Anaconda, this was my first workaround for the issue, once I need python for my test on university
`C:\Users\Leo>pip3 install numpy —no-cache-dir

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:

You can simply use
pip install numpy
Or for python3, use
pip3 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.

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 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

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.

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'
>>>

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.

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

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.
answered Apr 14, 2021 at 10:48
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.

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.

In this article, we will discuss how to fix the No module named numpy using Python.
Numpy is a module used for array processing. The error “No module named numpy ” will occur when there is no NumPy library in your environment i.e. the NumPy module is either not installed or some part of the installation is incomplete due to some interruption. We will discuss how to overcome this error.
In Python, we will use pip function to install any module
Syntax:
pip install module_name
Example: How to install NumPy
pip install numpy
Output:

To get the numpy description like the current version in our environment we can use show command
