[nhs000]

Summary

Due to scikit-image/scikit-image#2652 changes, using as_grey when calling skimage.io.imread at

caffe/python/caffe/io.py

Line 302 in 04ab089

img = skimage.img_as_float(skimage.io.imread(filename, as_grey=not color)).astype(np.float32)

causes the following error

TypeError: _open() got an unexpected keyword argument 'as_grey'*

• CUDA version (if applicable): 9.2
• Python version (if using pycaffe): 3.6
