Syntax for pyrunfile with multiple output variables?

30 views (last 30 days)
I am calling a python script from matlab using pyrunfile. The following works:
A = pyrunfile("pytorch_model.py", "A", X=Xpy, y=ypy)
B = pyrunfile("pytorch_model.py", "B", X=Xpy, y=ypy)
The following doesn't:
[A, B] = pyrunfile("pytorch_model.py", "A B", X=Xpy, y=ypy)
[A, B] = pyrunfile("pytorch_model.py", "A, B", X=Xpy, y=ypy)
Error: One or more output arguments not assigned during call to "pyrunfile".
What is the correct syntax for returning multiple variables? The documentation https://www.mathworks.com/help/matlab/ref/pyrunfile.html states that doing so is possible but does not show an example of how to format the string array containing the name of the python variables we want to return.

This is the way to do that (note that ["A" "B"] is a string array as specified in the documentation for that argument):
[A, B] = pyrunfile("pytorch_model.py", ["A" "B"], X=Xpy, y=ypy)

Did you try this?
[A, B] = pyrunfile("pytorch_model.py", ["A" "B"], X=Xpy, y=ypy)
Note that ["A" "B"] is a string array as specified by the documentation for that argument.
