Others have shown this error. I'm not sure exactly where it comes from,
but I suspect it comes from stats/distributions.py
where a constant is set _ZETA3 = special.zeta(3,1) on a module scope level
(and therefore executed on import). Your zeta functions
looks like it's behvaing erratically.
You could try:
special.zeta(3,1) to see what you get
If it's not working, it will just mean that the zeta function doesn't
work, which won't break all of scipy --- though I'd like to figure out
why it's giving this error.
