Pretty test result with pprint
🚀 Feature
Motivation
Test results are shown at the end of test loops since v0.7.0.
The content of the indication is prog_bar_metrics, which is basically inputted as a dict.
By default, this part uses built-in print function:

This way cannot display the pretty results so I suggest using pprint:

Pitch

Substitute print at the end of the test loop with pprint .

Alternatives
Modify here like:
        if test_mode:
            if self.proc_rank == 0:
                from pprint import pprint

                print('-' * 100)
                print('TEST RESULTS')
                pprint(prog_bar_metrics)
                print('-' * 100)
