@txfs1926 @xiezheng-cs 我测试只有警告，没有报错，如下所示；目前已经修正没有改警告 /Users/yizuotian/miniconda2/envs/pytorch/lib/python3.6/site-packages/skimage/io/_io.py:141: UserWarning: results/pic1-shufflenet_v2-gb.jpg is a low contrast image warn('%s is a low contrast image' % fname) Lossy conversion from float32 to uint8. Range [-0.569231390953064, 0.3581102788448334]. Convert image to uint8 prior to saving to suppress this warning.
