@Michalis Konstantinou, I figure out what happened with my issue... I had two instances of Python installed on my computer. So Matlab was pointing to the raw version of Python (without Numpy and others modules).
So I just configure the right version of Python and it's allright now. :)
pyenv('Version', 'C:\ProgramData\Anaconda3\python.exe')
I don't know if it's the same issue that you have, but you could try this solution. And obviously confirm that you do have installed Numpy module.

Hi @Eric Delgado, sorry for not answering sooner!
It was the same situation with mine, I had a raw version and a version from anaconda that included everything.
pyenv worked for me as well :)

Hi,
Here is a thing that you need to verify:
Check whether you have intalled "numpy", if not, you can install it viaa the following command:
> python -m pip install numpy
All the python dependencies needs to be installed seperately via "pip".
Additionally, make sure to setup the right python version before using it in MATLAB with "pyenv" command.
Hope it helps.
