Ah, sorry I don't know why I searched in the documentation but it didn't
come out or something went wrong to my eyes , anyways I searched in doc now
and it's right there.
The reason numexpr.test() fails is because I'm using numpy 2.0.0.dev where
complex_ has been removed.
So problem solved, I should change the behavior of numexpr.test().
