This is really weird, when I define the 3 level build matrix, the matrix.python variable is undefined when matrix.bitness is 32 while it is define correctly when matrix.bitness is 64...

It is working now, is it not?

Approximately, this should reduce the build process to 20 minutes, right?

Yes I found my typo.

I would say 25 min.

Two (minor) questions @ogrisel:

• Should MNT set OMP_NUM_THREADS=2 for cibuildwheel [cd build] #18807 speed-up the tests?
• Now that we have even more Wheel builder jobs, should we have a look to FIX Trigger CD build on master branch #18774 (comment) (CI Add workflow_dispatch event to manually trigger wheel builder #18801)?

Thank you!

Should #18807 speed-up the tests?

I am not sure it works as intended. I will debug it further. But I would not expect a big speed-up. It's more a protection if github actions workers are reconfigured to run on a 72 cores host with only 2 cores available via docker for instance.

That would be great indeed.

23 completed jobs in 28m 14s => nice! (instead of 50min for the total workflow previously).

Merged :)

I will rebase #18807 on top.
