get error when show a picture(image) : 'numpy.ndarray' object has no attribute 'mask' #10616
Description
Hi
I was using python3.5.2, numpy 1.14.1, and matplotlib 2.1.2 and encountered a problem when I attempted to show a picture with pyplot. It always gave errors saying 'numpy.ndarray object has no attribute mask', and the related source code seemed in 'matplotlib/image.py'.
I'm not sure whether it was caused by matplotlib or numpy. How do I fix this ?
