TODO: also configure logging for sub-processes(not master)

[DelinQu]

Hi victoresque,
Thanks for your hero repo! I used hydra_DDP branch to build my application, but got some problems in get_logger. Specifically, the program util.py loads the '.hydra/hydra.yaml' file from the directory, but hydra.yaml only exists in the 'output directory' such as 'outputs/2022-09-25/15-16-17' so python can't find it. I'm a little puzzled about the path of hydra.yaml. Maybe get_logger should load the /hydra.yaml from output directory? Could anyone help me! Thanks in advance!

(base) python train.py                     
Traceback (most recent call last):
  File "/mnt/petrelfs/qudelin/PJLAB/RS/VRS-Transformer/train.py", line 19, in <module>
    logger = get_logger("train")
  File "/mnt/petrelfs/qudelin/PJLAB/RS/VRS-Transformer/src/utils/util.py", line 19, in get_logger
    hydra_conf = OmegaConf.load('.hydra/hydra.yaml')

Hi @DelinQu, thank you for raising this issue.

It seems that get_logger is problematic as you pointed out and I'm currently working on this. I'll let you know if there is any progress.

Also, if you are interested in using hydra_DDP branch of this repo, I would recommend using my clone version of that. I made a few commits which solves serious bug(It was not using DDP at all) a while ago on that branch, but forgot to make a PR to apply that fix to this repo. I will make PR soon, but it could take some time.

Thanks for your replying SunQpark, I will follow your DDP! 😃

Hi SunQpark,
your repo has really helped me tremendously, but I got another problem when the training process is early stopped:
