can't use py.module inside a matlab code compiled for python

My matlab code uses 3 different python modules but I first compile it to a python library then use it from a python interpreter. my problem is that it gives me errors like:

Unable to resolve name

for lines that normally work in the uncompiled code. This happens when I try to use my custom python modules or even for matlab supported python functions like:

py.sys.path

I tried a workaround to load the modules in python then pass them as arguments to my compiled matlab code but this is unsupported and mypython interpreter gives me:

TypeError: unsupported Python data type: module

Any ideas on how to fix this ?
