Glad to see new and promising contributors emerge! ;)

@twiecki yeah, I used my work account by mistake!

Where do these mypy errors come from? CC @michaelosthege

Where do these mypy errors come from? CC @michaelosthege

Please just read the output of the mypy step. It says:

57/73 files pass as expected.
!!!!!!!!!
1 files unexpectedly passed the type checks:
pymc/_version.py
This is good news! Go to scripts/run_mypy.py and add them to the list.
!!!!!!!!!

But there are a bunch of black/pylint issues in that last pre-commit run.

@OriolAbril any idea why the RTD would be failing here? Does not seem to be related to versioning.

[OriolAbril]

I don't know, I'd have to build the docs locally to access all the logs. It might be related to the latest release of the theme. Try setting pydata-sphinx-theme<0.10.0 in the conda envs and if it works, open an issue so we remember to look into the actual error.

[ghost]

Yeah, the local build of docs is failing for me. Its looking for a lot of API stuff that does not exist anymore, like pandas_to_array, AR1, etc.

[twiecki]

abs_ was renamed to abs, is it still mentioned in the docs?

Not sure where the other ones are coming from. In any case, they are not related to this PR, so maybe we should fix that separately and merge this in.

[OriolAbril]

These are all only warnings which have always been around since the first v4 doc build, they fill the screen with red but don't break the website generation process. We also have an issue to track this #5282 because getting rid of those is easy but the symmetric case also happens, there are still many functions that are new instead of removed and do not appear on the docs, and or that there is no warning.

[twiecki]

So can we merge this safely?

[OriolAbril]

The build error should have been fixed in #6120 and builds for latest are working: https://readthedocs.org/projects/pymc/builds/ so it is now safe to merge this one even if rtd didn't work. We did have more than a week where the latest tag in the docs didn't match github as the rtd build failed and it could not be updated.

[ricardoV94]

@twiecki seems like you didn't squash this?

[twiecki]

Yes :(.

[ricardoV94]

Yes :(.

Oh well, time to start from scratch. PyMC5?

[OriolAbril]

Should we bring back the number as part of the package name too? 😜

[michaelosthege]

I've added the major label, because this changes how the pm.__version__ looks like.
Whoever makes the release please explain/link how to deal with version number comparisons for installs from GitHub =)

[maresb]

Are we sure that versioneer needs to be added to the install requirements? This doesn't look right to me.

[maresb]

Regarding my last comment, I started an experiment at #6135
