Problems with scipy package import when using mwpython

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 I get the following:
CEFNS-Mavericks:~ mws22$ mwpython
Python 2.7.10 (v2.7.10:15c95b7d81dc, May 23 2015, 09:33:12)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

As you can see, the import of scipy works fine, but throws an error that I can't seem to figure out. What is weird is that if I run >>python rather than >>mwpython the 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:
In mwpython, when I do import sys and sys.path I get:
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.

A related note: I am having the same problem with matplotlib. I can import matplotlib just fine, but matplotlib.pyplot throws the following:
>>> import matplotlib.pyplot as platform
