当运行卷积神经时出现了问题：Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above.
这一般就是cuda+cuDNN+TensorFlow的版本匹配不一致，当然大概率就是TensorFlow的版本过高了，降级即可：
sudo pip3 install --upgrade --force-reinstall tensorflow-gpu==1.9.0 --user
