"name 'ifilterfalse' is not defined" in Python3

[mxwell]

Hi,
I've tried to run PyTorch implementation in Python 3.6 and got the error:

    226     l = iter(l)
    227     if ignore_nan:
--> 228         l = ifilterfalse(isnan, l)
    229     try:
    230         n = 1

NameError: name 'ifilterfalse' is not defined

I think the function needs to be aliased after import in Python 3 like this:

from itertools import filterfalse as filterfalse

I suppose you meant from itertools import filterfalse as ifilterfalse. That is correct. I'm open to a PR if you want to send one. Cheers, Maxim
