Where would yaml config/in what document are the functions which convert yaml file to ML located?

[enricozammitlon]

The config.yaml is processed in the Gan4DS.py as it contains general configuration variables. The layouts are processed in NeuralNetworkLayout.py. For this issue I mean more documentation about what the yaml layouts should expect and in what format since there is a testing function for each yaml which is checked before each deploy and won't allow the run to deploy onto the gpu if these tests don't pass.
