unable to get matlab to recognize the python installed on my computer

I am working with Matlab R2021a in Windows. There is an installed python version on the computer.

It was installed using Anaconda, when i open an anaconda promt and use 'python -V' the answer i get is 'Python 3.8.8'.

When i use the command 'pyenv' in my matlab command window i get an empty PythonEnvironment structure.

I also tried downloading python version 3.8.0 from https://www.python.org/downloads/release/python-380/, following the instructions in the Matlab Help documentation, but still - using 'pyenv' results in an empty PythonEnvironment structure.

What am i doing wrong?

Thanks!

python on Windows might be tricky. Did you follow this page? Maybe you need to setup your PATH environment variable first?

[Hadas Ofir]

Yes, I followed the instructions, and also added the path to the 'python.exe' to the MATLAB path.

Still, it gives an empty result.

[Yongjian Feng]

Try this one please from matlab command line:

system('python -c "print(3.1415926)"')

[Hadas Ofir]

ok, after adding it ALSO to the path of the "system enviroument variables" it works.

[Yongjian Feng]

Yes, this is the path I meant. Matlab needs this to look for the python executable. Please accept the answer if it works.
