@mattip Any comments on this PR?

I am a bit concerned about why the tests are failing (which look like real failures not just from the upload logic).

test_subfigure_ss() was added after the arm64 wheel PR was merged. Not sure why it was not caught.

test_custom_transform() has a change where the tolerance was modified. Patch merged on June 29. Arm64 PR merged on July 24.

7deb36dcdebdf310993b1455043cb6eea2aa1b1a - Increase tolerance for ppc64le and s390x

aarch64 had specific tolerance before. After this patch, aarch64, ppc64le and s390x have the same tolerance of 0.034.
Failure log shows RMS (0.039) in test_custom_transform(). Not sure if my understanding of this is correct.

As this is the nightly wheels I'm going to go ahead and merge this so it is ready to go when we fix those regressions upstream (earlier today I incorrectly had in my head this was building a tag).

While the change to anaconda.org is good, this will need to be redone soon to move off travis since they have severely limited their free offering. Note that the upstream builds stopped running on travis three days ago, I imagine these will also reach their credit limit soon.

@tacaswell Is there a timeline for when the aarch64 wheels show up in PyPI?

@tacaswell @mattip Will there be an aarch64 wheel released for matplotlib?

@tacaswell @mattip Ping. Any timeline for when aarch64 wheels will be available for matplotlib?

My guess is with the next release of matplotlib. You may want to reach out in other forums like the mailing list https://mail.python.org/mailman/listinfo/matplotlib-devel

Are there aarch64 wheels someplace to upload? I am not seeing them at https://anaconda.org/multibuild-wheels-staging/repo?type=pypi to upload.

It turns out there was a problem with the .travis.yml file - there were missing semicolons at the end of the lines in this PR. I am working on a follow up to move the linux, macos jobs to github actions and fix the travis builds for arm64.

It seems there are no CI-built wheels for windows. Is there a recipe for building them somewhere?

@tacaswell Since you are using cibuildwheel in the main repo, what is the added value of this repo? Can't you upload to anaconda.org directly from the main repo?

That was to spread out the builds across CI; with Travis being all but dead, those could be switched on for non-tagged commits too.

So it would seem to me to make sense to continue with cibuildwheel as a preferred solution and consolitate activity there. I commented on matplotlib/matplotlib#19147.

@mattip Will there be aarch64 wheels in the next release?
