How to not create lightning_logs when using a external logger like wandb ?

[richarddwang]

I would like my wandb logger to just place their data under wandb dir, and checkpointcallback to save ckpts under dir_path I specified.
And I don't want pl to create lightning_logs and files under it, but I can't set logger=False b/c I use a logger. Is there any suggestion ?

You can set the save_dir in WandbLogger, something like

logger = WandbLogger(save_dir="wandb", ...)
Trainer(logger=logger, ...)

This should work (haven't tested it).
Then your logs and checkpoints will save to two different locations.

Hi, I found WandbLogger's save_dir defaults to wandb.
I accidentally forgot to delete lightning_logs and thought it was generated by the current run with wandb. Actually we just need to specify WandbLogger as logger, dirpath of ModelCheckpoint, and then lightning_logs won't be generated.
Anyway, thanks for your reply !
