Dose PL validate and train at the same time?

This is part of console output:

It looks like it train and val at the same time.

hey @sss

if you have validation enabled, it will run the validation loop after training in a general case. The main progress bar in this case will display num_training_steps + num_validation_steps.

Also, we have moved the discussions to GitHub Discussions. You might want to check that out instead to get a quick response. The forums will be marked read-only after some time.

Thank you
