Unresolved references for mpl_toolkits and cm
(am betting cm is from mpl_toolkits)
I have tried Invalidating Caches & Restarting (as well as manually readding the path to mpl_toolkits)
with no success.

Was it helpful?

Solution

I hadnt imported cm
from matplotlib import cm
and i needed to import mplot3d like
from mplot3d import Axes3D instead of
from mpl_toolkits.mplot3d import Axes3D
My data was not ranged correctly too (why nothing was showing). Needed to range form -10 to 10, i had left out the minus sign.
