When I try to use this example (link: https://ww2.mathworks.cn/help/images/develop-raw-camera-processing-pipeline-using-deep-learning.html) to train a neural network. I changed the value of "doTraining" to "true". But an error is reported on line 204. The error message is "The function or variable ‘valSetSize’ is not recognized".
I confirmed that the variable "valSetSize" is not defined in the context.
So how can I know how to set this parameter?
Any answers are helpful.
