@slel, do you see this in the logs of notebook also in your local build?

This fixes the problem, as can be seen in https://github.com/mkoeppe/sage/runs/4349318130?check_suite_focus=true

not yet released pip, where this megapatch is from, is dropping python 3.6.

Can we either follow the suit, or make this patch cygwin only?

comment:14

We dropped support for Python 3.6 in #30551.

Dropping support for Python 3.7 is #32937.
