@pifparfait have you checked if https://www.piwheels.org/simple/install/install-1.3.4-py3-none-any.whl has python_requires matching your current Python interpreter? This may be similar to #11321.

pip3 install -U tensorflow install -U tensorflow==2.3.1

This reproducer command is weird. You probably didn't mean to include that second install -U — with that in your command, pip attempts to install a package called install (which is also visible in your log).
