ImportError: No module named 'matlab.engine'; 'matlab' is not a package (Windows)

Hello,

i've installed MATLAB Engine API for Python (Windows 7) according to

https://de.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html

Matlab-Version: R2018a

Python Version: 3.5.1

Now i'm trying to initialize a connection according to

https://de.mathworks.com/help/matlab/matlab_external/connect-python-to-running-matlab-session.html

What follows is this Error-Message:

    ImportError: No module named 'matlab.engine'; 'matlab' is not a package

What works is

   import matlab

but not

   import matlab.engine

I have two Python installation on the computer and did the above installation for both of them (calling the python.exe from the specific folder, the installation for the python version used was last). Some hints for this problem exist, but only for linux.

Has anybody an idea? Thanks

What is the Name of your python script?

[John Deer]

I'm using ITOM in the commando shell (no script)

https://itom.bitbucket.io/

The Problem is not ITOM-related, because on an onther PC everything works fine. Thr Problem rely in the underlying python

[Stephan]

I had a similar problem when I installed the package - see here . I could fix this by renaming my py script, which was called matlab.py, so I had to learn that this was the problem.

That's why I asked for the name of the script. Maybe you could search the computer if there is a py file called like that. If that is not the case, unfortunately I can not help you.

[John Deer]

There is a file in

C:\Program Files\Python35\Lib\site-packages\pygments\lexers\matlab.py

But renaming it an restart ITOM (python) didn't have any effect (maybe i have to restart the computer, or at least log off / log on)

There is NO file like

C:\Program Files\Python35\Lib\site-packages\pygments\lexers\matlabengine.py

And copying matlabengine.py to this directory doesn't have an effect either

[John Deer]

Supplement:

On the PC with the working system, the file

C:\Program Files\Python35\Lib\site-packages\pygments\lexers\matlab.py

exists too.

On both PC's (working and non working) the following files exist:

C:\Program Files\Python35\Lib\site-packages\matlab\engine\matlabengines.py

Sorry, then i have no idea what you could do to solve this. But it was worth a try. Good luck for solving this. If yo find a solution please post it here.

Best regards

Stephan

Now i've got the answer to the riddle:

ITOM does have an own matlab-support:

   https://itom.bitbucket.io/latest/docs/08_scriptLanguage/pymod-matlab.html

On the corresponding PC, a colleague did already the setup for the ITOM-connection. The other connection is in conflict with this.

Thats good to see - will help people in future if they have the same trouble!
