Description

skimage/transform/_warps.py contains a lots of future warnings about next versions that are not labelled as FutureWarning. When one needs to suppress future warnings (to see user warnings), one would normally use

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

However, in skimage all future warnings are not marked properly, so it will mess this up.

Solution

replace warn(x) with warn(x, FutureWarning)
