pyrunsfile doesn't work when python script includes "import"

Hi.

I want to run a python script using pyrunfile.

I have confirmed that a very simple python script works through pyrunfile.

such as Ex.py :

% Ex.py
x = 1+1;
print(x);

However, if I add the code to import additionally installed libraries such as numpy, matplotlib, and tensorflow, the following error occurs.

Python Error: ModuleNotFoundError: No module named 'numpy'

I have obviously installed numpy, and when I run the python script through pycharm it works fine.

Like many advices before, I tried creating a virtual environment via anaconda prompt, installing numpy first and then running matlab, but the same problem persisted.

Am I missing something when I load the python environment to matlab?

I am using matlab 2021b, and python 3.7.9

Please help.

Thank you.

Hello,

As I know, there were some python packages that some versions of matlab can't load if you installed them in virtual environment (such as from conda), and numpy was certainly one of them.

I am not sure how newer matlab deal with it, but I will suggest you try to avoid anaconda and only use the original python, pip, then make matlab load it.
