Missing declaration of "valSetSize" in Example "Develop Raw Camera Processing Pipeline Using Deep Learning"

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.

Thank you.

Please use the variable numValImages instead of valSetSize.

The variable name valSetSize used in the example is not correct.

Hope this helps!
