I've searched for duplicates, did not found one. In another hand, manually install numpy works, but is far from ideal. Now I've got a similar issue with cython, still with the same install command.

Correction : I've finally found the issue (did not find it with my initial search) : #25193

[TomAugspurger]

#2519

#25227 for the numpy side. No PR yet for the Cython issue.
