Hello,
I am trying to call a python function in matlab. I tried the example provided in mathworks website which has a file called mymod.py and a function search. I have another file with another function I want to run.. both in the same location.
The mymod.py seems to work perfectly.. but the python file I have keeps giving me this error Undefined variable "py" or class
"py.four.trainNetwork".
I do have to mention that this python code imports from pybrain which is installed on my computer.
I am running matlab on a mac.
Thanks.

As per my understanding, this error message might occur due to some issue in user defined python script. You can try the below command:
>> py.importlib.import_module('ScriptName')
Also, you can go through this MATLAB documentation page, which suggests other possible reasons for the mentioned error message.
