validating bar keep showing 0 when check_val_every_n_epoch is bigger than 1
🐛 Bug
Normally, the validating bar should update according to the procedure of validation_step, but when I set check_val_every_n_epoch bigger than 1, 2 for example, it keeps showing 0it.
I encountered this issue under a terminal environment.
