Importing the multiarray NumPy extension module failed

Check your system requirements.

Make sure that you have the correct version of NumPy for your system. You can find the latest release of NumPy here.

If you are using Anaconda, then you can install NumPy by running the following command in your terminal:

conda install numpy

If you are using pip, then you can install NumPy by running the following command in your terminal:

pip install numpy

Install the module

If you’re getting an error when trying to import the multiarray numpy extension module, it’s likely because you don’t have the module installed. You can install it using pip:

pip install numpy

Alternatively, you can download the source code from and install it manually. Once you’ve done that, you should be able to import the module without any problems.

Check your installation

The error message “importing the multiarray numpy extension failed” can be caused by a number of different things. Here are some things to check:

-Make sure that you have numpy installed. The easiest way to do this is to use a package manager like pip or conda.
-If you’re using an older version of numpy, upgrade to the latest version.
-Make sure that your numpy installation is in your Python path. You can check this by running the following command: import sys print(sys.path)
-If you’re still having trouble, try uninstalling and then re-installing numpy.

Check your system PATH

When you get the error “Importing the multiarray numpy extension module failed”, it means that there’s something wrong with your system’s PATH. The PATH is a list of directories that Python checks when it’s looking for modules to import.

One way to fix this problem is to add the directory where the NumPy module is located to your PATH. For example, if NumPy is located in C:\Python27\Lib\site-packages
, you would add this directory to your PATH:


You can also try reinstalling NumPy.


The numpy multarray extension failed to import. This is probably because your PYTHONPATH is set incorrectly. Make sure that your PYTHONPATH includes the directory that contains the numpy multarray extension.

Check your environment variables

It looks like you may not have the proper environment variables set up for your system. Make sure that you have the following environment variables set:

  • PYTHONPATH=/path/to/numpy/lib:/path/to/numpy/build/lib.${PY_VER}${ABIFLAGS}
