Thanks @calvh, really nice. Lgtm, sorry for the delay.

Do you mind merging master? I think the CI should be green now.

[calvh]

Thank you @datapythonista! I am sorry this may be a dumb question, but do you mean I should merge with the latest master so that the CI will pass? If so, should I be doing merge (fast-forward) or rebase?

[datapythonista]

Your branch was created two weeks ago, so your changes (the diff in this PR) are proposed on that old master. That master was broken for some problems with the development branch of numpy, that's why the CI is red.

So, the idea is that you updated your branch, so it contains all the changes in master for the last two weeks. The CI should be then green, and also, if anything changed in master that affects this PR, we should have it in the diff and in the CI.

In practice, that's simply git fetch upstream, and then git merge upstream/master being in your branch. And then you git push to update this PR.

Does it make sense?

[calvh]

@datapythonista I need some help, I merged master but some CI checks are still failing. Should I merge again with the latest master and try again? Thank you in advance.

[datapythonista]

I can't check in detail now, but seems like all last PRs are red, so I guess something is broken in master. You'll have to wait until it's fixed, and thrn merge master again.

[calvh]

@datapythonista thought I'd try again after merging with the latest master, but still no luck :(

The error from one of the failing check occurs when running the bash script to create the conda environment

("Connection broken: ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None)", ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))

I wonder what I can do to fix this problem?

[datapythonista]

Let's rerun and see, seems like conda servers are having problems recently.

[calvh]

Thank you!

All the tests passed except one. Looks like an issue with one of the scalar/timedelta tests. There is currently a PR to fix it (#42413). Once that is merged to master I will merge and push again.

[calvh]

@datapythonista all the tests passed. Thank you for your guidance and assistance!
