…n error The @on_main_process decorator on init_trackers was preventing tracker initialization in non-main processes, leaving the trackers array empty. This caused accelerate.get_track() to return GeneralTracker for non-main processes, resulting in attribute errors like `'GeneralTracker' object has no attribute 'log_images'.` Since GeneralTracker and its subclasses already handle calls from non-main processes appropriately, the decorator was creating unintended behavior. Removing @on_main_process ensures init_trackers runs in all processes, maintaining proper tracker initialization and preventing these errors.
