Python Error: ModuleNotFoundError: No module named 'sklearn'

Hi,

I was calling Python from MATLAB but I got the above error.

I have installed sklearn using PyCharm and it ran normally using Python.

What should I do to enable the package on MATLAB?

Hey @Zair Ahmedi, I am having the same issue... I can import "math module", but not "numpy module", for example. Did you find a solution?! I don't want to reinstall Matlab or Python! :)

@Zair Ahmedi, 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')

Hi Zair

I understand that when you are using "sklearn" package in MATLAB you are getting the above error.

It is possible that the "sklearn" package is not in the Python search path which is being used by MATLAB.

Here are two possible options to resolve this issue:

1. Initialize python environment in MATLAB using "pyenv" command with the Python version that has "sklearn" package installed.
2. Include the "sklearn" installation in the Python search path using "py.sys.path" command in MATLAB. Here is an example provided below ("sklearnPath" is the directory where sklearn package is installed):

insert(py.sys.path,int64(0),sklearnPath) 

Please refer to the below documentation for more details:
