Fixes: #2927
This update calculates the number of iterations per epoch dynamically instead of hardcoding it to 250.
The method
get_tr_and_val_datasetsin thennUNetTrainerclass was modified to update bothself.num_iterations_per_epochandself.num_val_iterations_per_epochbased on the dataset size and batch size.Additionally, progress bars were added to the training and validation loops to provide users with a clearer indication of progress during long training sessions.
