问题
I have experienced very strange problem related to scikit-image. Namely, I'm not able to run "started example":
from skimage import data, io, filter
image = data.coins() # or any NumPy array!
edges = filter.sobel(image)
io.imshow(edges)
After that Python 2.7 reports Error:
ValueError: can not convert object to float64.
Moreover, I am not able to open any "tif, png" images, because Python reports similar error. Interestingly, this problem appeared suddenly, because at the beginning everything was working correct.I suppose this was due to instalation of pymorph module which probably affected numpy. However, do You have any ideas how to solve this problem?
