How to stop weights & biases (wandb) from creating random tmp files?

I have a million tmp files due to wandb on my home folder. I don’t know why. Why are they being created & how do I stop it?

Hi @brando thank you for reporting this. Besides these directories which are controlled by the environment variables WANDB_DIR, WANDB_CACHE_DIR and WANDB_CONFIG_DIR, the wandb SDK in some cases such as logging wandb.Image objects or Artifacts it will additionally write some temporary files in the tmp directory for code’s efficiency reasons.

It seems that in your system, these were created in your home directory. Could you please post here the output of ls -lah /t* to check the write permissions, and of pwd from within the directory where these files were generated? I have filed a feature request to our engineering team to expose an environment variable for this directory so that it can be controlled where to write the temp files. Please let me know if that would help. Also, in terms of logged data, has everything uploaded fine in W&B, and in that case would you need any help to remove these temp files?


I’m encountering this logging thing in my /tmp folder when downloading artifacts. From your explanation, I guess it’s the intended behaviour, but is there any way to just avoid wandb to produce these files?


Hi @jceamoran indeed that’s intended and it isn’t currently possible to switch this off. You can however remove these files once your training has completed and everything has synced with W&B App. May I please ask what’s the reason that you wouldn’t want to have some temporary files written in your disk? I can add this context to an existing feature request to allow users control the location of this directory, would this work for you?

Hi @thanos-wandb !

I was just wondering how to make my deployments lighter. Nothing I cannot live with. However, being able to choose location of these files would be an interesting feature tho!

Thanks for your answer :slight_smile:

Hi @jceamoran thanks for the context, good to hear it’s not currently blocking you. You could in the meantime call a command as follows, to cleanup the /tmp folder after your training has finished and synced everything to W&B App:
os.system('find /tmp -type d -name "*wandb*" -exec rm -rf {} \;')

However, I understand that this might not be ideal to be done by you, so I have also increased the requests for this feature, and we will reach out to you here on any related updates!

Hi, I just noticed this behavior too. We have literally millions of wandb directories in /tmp, so just listing the contents of the directory is slow, even though the total space they take up is only a few GB. I guess it would be nice if wandb did not produce so much trash, and also if it does, maybe they could be stored in per-user subdirectories of /tmp instead of directly in /tmp
