# Some notes about this new architecture:
|
||||
# 1) Discriminator is going to need to get update_for_step() called.
|
||||
# 2) Not sure if pixgan part of discriminator is going to work properly, make sure to test at multiple add levels.
|
||||
# 3) Also not sure if growth modules will be properly saved/trained, be sure to test this.
|
||||
# 4) start_step will need to get set properly when constructing these models, even when resuming - OR another method needs to be added to resume properly.
