It has been reported for some people failure at training:
```
tensorflow.python.framework.errors_impl.UnknownError: 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.

Setting the `TF_FORCE_GPU_ALLOW_GROWTH` environment variable to `true` seems to help in such cases.
