I was wondering if you're using detrex to train on your custom datasets~

Yes, I am using detrex to train on my custom datasets.

from detrex.

@ChenWanger I'm trying to reproducing your problems now and try to solve it~

Maybe you can also refer to detectron2 custom datasets for more details about register your own datasets in d2.

I'm closing this issue~ feel free to reopen it if needed~
