I'm going to take a look at this later, thank you @ku-ya

Update: I've been trying to see if I can make this run every 15 minutes, but unfortunately that doesn't seem to be working on my branch? (This is the first time I have tried to schedule github actions, I might be making some mistakes)

After we can confirm it works, we can make the interval once per month and merge.

Thanks for the help @ku-ya! 🙏

We moved to GitHub Actions in PR ( https://github.com/dask/dask-image/pull/188 ). That said, if you spot anything we should add, please feel free to either update this PR to apply changes on latest main or open a new PR, whichever is easier.

Thanks again! 😄

Can one of the admins verify this patch?

Admins can comment ok to test to allow this one PR to run or add to allowlist to allow all future PRs from the same author to run.

I remember this from the sprint. There have been a few changes since then to the way we handle CI, so it's probably best to close this out.

Thanks for your code sprint contributions @ku-ya, it was great having you there 😄
