Features: Subdivide Hydra log directory

[jieonh]

What

• Subdividing Hydra logging directory
• The results are likely to be as follows.
  • single run: logs/train/run/{custom_exp_name}/2023-01-05_05-57-24
  • multi run: logs/train/multirun/{custom_exp_name}/{multirun-tiral-number}/2023-01-05_05-57-24

Why

Currently, the outermost logging folder name is set to the time stamp, making it inconvenient to distinguish.

How

• Seperate multirun / run dir
• Add custom experiment name
• Simplify multirun subdir (override_dirname -> numbere)
• Check for conflicts or errors due to changes

Nice! Do I need to revise the ROC Curve save directory?

I think this is a great idea, and hope that it could make the logdirs look neater.
Just a minor question: Is the custom exp name going to be automatically generated? Or should we manually set the name of the experiment?

@seoulsky-field
No, this probably will be an independent task from inference logging (including ROC curve saving dir).
Do you have any specific plan for plot saving directory? If not, I will add that one in this issue too!

@chrstnkgn
About exp name, It was intended to set it manually so that the user could set the name according to the purpose of the experiment. However, I think it will also be a good idea to name it automatically or generate a file name as 'unclassified' when exp name is not specified.
If you have any good idea for this, please feel free to make suggestion!

Thanks to reply. I just plan to change dir names "roc_curve_imgs-trial1" from "imgs".
Maybe trial1 will be replaced its trial numbers such as trial1, trial2, trial3, etc.
Because of Grad-CAM, I decided to change like that.
