Attempt to execute SCRIPT trainNetwork as a function: C:\Program Files\Poly​space\R201​9b\toolbox​\nnet\cnn\​trainNetwo​rk.m

Answer 1

Hi Atiya,

The error message indicates that MATLAB is trying to run "trainNetwork" as a script rather than as a function. For more information on the differences between scripts and functions, please refer to the following documentation:

https://www.mathworks.com/help/matlab/matlab_prog/scripts-and-functions.html

One possible cause of this issue is the presence of a user-defined M-file named "trainNetwork.m" that is conflicting with the built-in function. To resolve this, rename any user-defined functions that appear higher on the MATLAB path than the built-in function to prevent such conflicts.

To determine the location(s) of the "trainNetwork" function that MATLAB is referencing, run the following command in MATLAB:

which -all trainNetwork

/MATLAB/toolbox/nnet/cnn/trainNetwork.m

I hope this helps!

We can see from the path that was reported, that this is not a case of a third party file on the path shadowing the appropriate file.

It is possible that the appropriate file is corrupted, in which case the toolbox would need to be reinstalled.

Before reinstalling, experiment with

rehash toolboxcache

in case the cache of toolboxes has been corrupted.
