Using feedforwardnet in python API

Hi i'd like to use the matlab feedforwardnet objection from python, but when i try and create it i get the error:

only 1xN and Nx1 cell arrays can be returned from MATLAB

Here is the relevant code section:

import matlab.engine

import matplotlib.pyplot as plt

import numpy as np

eng = matlab.engine.start_matlab()

ffnet = eng.feedforwardnet(20.0)

Hi Yannik,

I understand that you are encountering an error when calling the ‘feedforwardnet’ function from MATLAB using python.

It seems the error is due to the line:

ffnet = eng.feedforwardnet(20.0) 

To resolve this issue, you can modify the code as follows:

layer_size = matlab.double(20) 
ffnet = eng.feedforwardnet(layer_size) 

I also found a similar query on MathWorks community that you can refer to for additional guidance:

Hope this helps!
