Prerequisite
- I have searched Issues and Discussions but cannot get the expected help.
- The bug has not been fixed in the latest version(https://github.com/open-mmlab/mmengine).
Environment
mmengine == 0.9.0, but the related code in the latest version is the same.
Reproduces the problem - code sample
Set EpochBasedTrainLoop.val_begin to 0 and run it.
Reproduces the problem - command or script
Set EpochBasedTrainLoop.val_begin to 0 and run it.
Reproduces the problem - error message
The val_loop is still launched after the first epoch.
Additional information
I'm currently using EpochBasedTrainLoop to train my model. After I added a custom Metric, I want to test it before training. So I need to run val_loop before the first epoch. I set the val_begin to 0 but nothing happens.
I checked the code. Move self.run_epoch() line 96 to line 103 in loops.py should fix this bug.
