I have tried the various methods posted for this error, but to no avail.
Does anyone have any good wisdom to share?

Start with dreambooth_gui.py at open_configuration and train_network.py at train, then inspect the DreamBoothDataset constructor used by train_network.py. Reproduce the reported configuration and training flow to determine whether the unbound local variable and argument-count error are related. Done means the flow proceeds without either traceback and no longer ends with the reported subprocess error.
