Hotfix: Error when trying to use Ray Tune

[chrstnkgn]

What

My command was: python main.py Dataset.train_size=3000 Dataset.root_path='/home/' hparams_search=raytune

Then the following error message arises from custom_metrics.py file with long and boring and uninterpretable hydra errors then finally

Why

I've actually seen this error several times, it seems to be a conflict error when using hydra and ray simultaneously when we try to get the time information using hydra and apply it into the ray system. I have not found the appropriate solution though, I've just been avoiding using it in such way.

How

I think we need to seek for ways to resolve this error instead of simply avoiding it so that we know what to do when the same thing happens.

I'm checking this error. Please wait a second!

Thanks, @chrstnkgn for reporting this error. FYI, I also encountered the same error with the command

python main.py hparams_search=raytune Dataset.root_path='/home/'

@chrstnkgn Thanks to check and wait! I checked the problem and solve this. I'll update code develop branch directly.
