### Describe the bug ### Problem: I tried launching this repo via Gitpod: it failed on account of `attr` not being installed. ### Most likely cause: The `attr` lib is not listed as a requirement for `python-attrs`. ### Reason for posting here: This issue post is to: - let you know that I have posted [python-attrs issue 923](https://github.com/python-attrs/attrs/issues/923) to let them know. - let them know at least one consumer is waiting for them (after I obtain this issue number). ### Reproduce the bug Launch the repo via Gitpod. ### List your environment _No response_
