Why does my parpool crash when I am running Python from within MATLAB using Anaconda Python?

My parallel pool keeps crashing every time I run my MATLAB code that calls Python functions inside it. My Python installation was installed using Anaconda.

My crash log is shown below:

Generally, although it is possible to configure MATLAB to work with Anaconda/Miniconda Python, the recommended approach is to install CPython distributions. You may download it using the Download Python page .

Refer to the

Compatible Python versions for your MATLAB versions

 documentation to learn more about version compatibility.

In addition, it may be required to ensure MATLAB uses the correct version of Python as follows:

pyenv(Version="executable")

Here, "executable" is the full path to the Python executable file associated with the correct installation of Python. For more information refer to the Configure your system to use Python documentation.
