Error importing matlab.engine into Python on windows

I'm on Intel core i7 64 bits using MatlabR2014b and Python 3.3.5.amd64. I have already installed API from here , but still got these error messenger.

    >>> import matlab.engine
Traceback (most recent call last):

    pythonengine = importlib.import_module("matlabengineforpython"+_PYTHONVERSION)

Is this problem solved?

Add your matlab sub-directory ${matlabroot}\bin\win64, which is possibly,

C:\Program Files\MATLAB\R2018a\bin\win64

to the PATH variable.

It worked for me.

It didn't work for me...

Answer 2

It looks like that there is a conflict between libraries used by MATLAB and libraries located in your system. You may run Python in verbose mode with "-vvv" to get more information like this:

 %python -vvv
 >>>import matlab.engine
 >>>import matlabengineforpython3_3

If this does not help, you may use Process Monitor to check what happened when the Python Engine library failed to load.

I countered same problem, it seems matlabengineforpython3_3 was not generated.

I wonder whether this problem is solved?
