"1" also makes cuDNN convolution and max-pooling operate deterministically.
    This makes Keras Conv\*D and MaxPool\*D layers operate deterministically in
    both the forward and backward directions when running on a CUDA-enabled GPU.

## Breaking Changes

*   Deletes `Operation.traceback_with_start_lines` for which we know of no
    usages.
