tGANs - Generator model not compiled?

[fotais]

Thank you for the very interesting tutorial and code concerning tGANs!
I am trying to replicate the example with diabetes csv, but in every epoch I am getting a warning:
WARNING:tensorflow:Compiled the loaded model, but the compiled metrics have yet to be built. model.compile_metrics will be empty until you train or evaluate the model.
when saving the generator model.

Then, on load I get:
WARNING:tensorflow:No training configuration found in the save file, so the model was *not* compiled. Compile it manually.

Should the g_model be also compiled in the define_generator , before saved in every epoch?
