Issue #, if available:
to_dict() converts Python None to the string "None" via str(), which gets sent as a hyperparameter value to the training container causing failures (e.g., resume_from_path="None" triggers invalid checkpoint resume). This fix omits None-valued hyperparameters instead of serializing them.
