Using the python API to delete runs without a particular tag

How do I use the Python API to find and delete runs without a particular tag?

I tried writing this MongoDB query, but it doesn’t appear to work:

for r in (api.runs(
    filters={"tags": {"$in": "keep"}}

This is similar to this post

According to ChatGPT, I can use the following:

api.runs(entity_project, filters={"tags": "keep"}

However, it is not clear to me whether that means the tags must be “keep” and nothing else, or whether it matches all runs with “keep” in the list. I would love an example of this kind of query in the [code]( wandb/ at latest · wandb/wandb (

Hi @turian, thanks for your question! You can delete runs without a concrete tag with a code like:

import wandb
api = wandb.Api()
runs = api.runs('entity_name/project_name')
for run in runs:
  if "keep" not in run.tags:

Could you please try it and see if it works?
