Good day!
I need to use "py" function to call python module in MATLAB.
It worked until I used "py" command inside the body of an SPMD statment.
I got an error messege: MATLAB cannot determine whether "py" refers to a function or variable.
How can I solve this problem and be able to call python module even in the body of an SPMD statement?
Sincerely,
Minjeong

Verfiy that none of these points mentioned in this link is causing the issue.
I tried to use "py" command inside spmd statement in this way and it worked fine. To make sure the python module is in the path
P = py.sys.path;
if count(P,'path of your python module') == 0
insert(P,int32(0),'path of your python module');
end
spmd
N = py.list({'Jones','Johnson','James'});
py.mymod.search(N)
end
This is the python script
# mymod.py
"""Python module demonstrates passing MATLAB types to Python functions"""
def search(words):
"""Return list of words containing 'son'"""
newlist = [w for w in words if 'son' in w]
return newlist
