scipy fftn produces warning that numpy fftn does not

Thanks for reporting this warning. For book-keeping, not seen with python 3.5.5, scipy 1.0 and numpy 1.14.1 does not show this warning. Interesting to see that fft version from numpy is without warning. I'm keeping this issue open for now.

I have not thought too much about which is better in this case.

no more warnings with current version of python (3.7.3) and latest scipy/numpy version.
closing for now
