Incompatibility between functools.partial and scipy

Question

I need to pass the inverse of a cdf as an argument to function. I cannot understand why this does not work:

def InvNormal(q,a,b):
    return  norm.ppf(q,a,b)
F_invs = functools.partial(InvNormal,0,1)

Doing

print(InvNormal(0.3,0,1))
print(F_invs(0.3))

I get

-0.5244005127080409
-inf

Any help is appreciated! Bernardo

I tried it with different random variables.
