Importing scipy.signal fails #35

Closed m-macaskill closed 8 years ago

m-macaskill commented 8 years ago

import scipy works but not import scipy.signal or from scipy import signal. The error message below occurs. Does this indicate the need for some dependency that isn't contained within the Pineapple installation itself?

Right now Pineapple is not including gfortran libraries, looks like it needs to.

One workaround for the current version is to run "brew install gcc" to get gfortran installed into /usr/local/lib.

Recent changes should fix this for the next release. Leave a comment if you still see problems after the next release.

Same problem still present for me, using Pineapple-0.8.0 (2015-10-11T14:25:44).

Seeing this still in Pineapple-0.8.0
