Hi 🙂

I was wondering if it’s possible to delete an artifact that is a reference to an S3 object.  
I mean deleting it within weight and biases but also from S3.

If it’s not built-in, is there any webhook that I can use to delete my model in S3 when deleting it from W&B?

The flow would be :

1. Train =\> Push metrics to W&B, push model to S3, add the S3 reference of the model as an artifact in W&B.
2. Evaluate, do some comparison, ML magic, etc…
3. Deciding to delete the run as another was better. Delete in W&B, which will remove all the run and all the files in S3 associated with this run.

Thanks in advance for any help.

Have a great day 🙂

Hi @ierezell,

This is not supported inside of wandb. You can use [Boto3’s S3](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html) API to delete objects from S3.

W&B does not store the data from any artifact references, only metadata related to the artifacts. As a result, we can not operate on that data.

Thanks,  
Ramit

Hi @ramit_goolry,

Thanks for the clarification 🙂

Is there any possibility to have a webhook then?  
So when a delete is called wandb executes my hook to delete the corresponding S3 files ?

Thanks in advance,  
have a great day

Hi @ierezell,

I apologize, but we don’t support web hooks to S3 currently. The most secure way to programmatically delete your artifacts would be through Amazon’s Boto3 API.

Thanks,
