Matlab crashes when importing pytorch library

I'm calling user-defined python module from matlab script that includes PyTorch library. The following line crashes Matlab:

def myfunc():
    device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")

Any ideas on how to fix this?

Thanks in advance

Using out-of-process execution mode will avoid these conflicts. For this reason, using out-of-process mode is the best practice when using the Python Interface. Use the pyenv command to run in out-of-process mode.

>> pyenv("Version","<path to python executable>", "ExecutionMode", "OutOfProcess")

Thank you @Vignesh Murugavel for the answer

Yes, this fixes the issue of matlab crashing but then I need to call matlab script in my python code , so as soon as I include the matlab engine in python module python interpreter terminates

eng = matlab.engine.start_matlab()
eng.cd(r'/home/pathToMyMatlab', nargout=0)

with the following error:

Python process terminated unexpectedly. To restart the Python interpreter, first call "terminate(pyenv)" and then call a Python function.

This does not happen when ExecutionMode of python interpreter is the default InProcess.

Please help!
