I have created a Python package with MATLAB Compiler SDK (R2018a). I have been able to include that package and execute functions in Python, but have been having trouble with including other Python packages in my Python script. I am on a Mac and as such I have to use the Matlab script mwpython to run my Matlab generated Python packages. When I try to import scipy.io I get the following:
CEFNS-Mavericks:~ mws22$ mwpython

As you can see, the import of scipy works fine, but scipy.io throws an error that I can't seem to figure out. What is weird is that if I run >>python rather than >>mwpython the scipy.io imports just fine. That lead me to think it was a problem with my sys path variable. In mwpython, when I do import sys and sys.path I get:
'/Users/mws22/anaconda2/lib/python2.7/site-packages'
'/Library/Python/2.7/site-packages'
'/Users/mws22/anaconda2/lib/python27.zip'

In mwpython, when I do import sys and sys.path I get:

'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages'
They both point to /Users/mws22/anaconda2/lib/python2.7/site-packages where I know scipy is installed (io is a subdirectory of scipy).
I am at a loss as to what to do to be able to use scipy and my MATLAB generated python packages in the same program. Any help would be appreciated.
