Ugh - I'm so sorry @davidcavazos but after all of that model training, I don't see it in the project! I'm assuming it's in the python-docs-samples-tests project, but if not, let me know.

I don't think that any @GoogleCloudPlatform/python-samples-owners have been touching the Vertex AI models, but I wonder if something like the "reaper" that Luke Davis had used awhile ago could be silently deleting it? @vinnysenthil @dizcology @aribray, is there a job that runs and deletes models in the test project? Or were you only using such a tool in your Vertex AI team project?

I remember @ivanmkc brought up a topic about cleaning up some stale/old/expensive looking test data sets on our project folder as well to lower the budget, perhaps it was deleted by then?

I think it got deleted, I had the new model called permanent_wildlife_classifier_DO_NOT_DELETE and tests were passing before. I thought the reaper ignored anything prefixed by perm, but maybe the rules are different.
