The attr `block_size` indicates the input block size and how the data is moved.

  * Chunks of data of size `block_size * block_size` from depth are rearranged
    into non-overlapping blocks of size `block_size x block_size`
  * The width of the output tensor is `input_depth * block_size`, whereas the
    height is `input_height * block_size`.

                  `False` in the corresponding RouteParentStatus.


                  In the event that multiple HTTPRoutes specify intersecting hostnames (e.g.
                  overlapping wildcard matching and exact matching hostnames), precedence must
                  be given to rules from the HTTPRoute with the largest number of:


                  * Characters in a matching non-wildcard hostname.

        usage.
    *   Experimental support of
        [all reduce gradient packing](https://www.tensorflow.org/api_docs/python/tf/distribute/experimental/CollectiveHints)
        to allow overlapping gradient aggregation with backward path
        computation.
    *   Deprecated `experimental_run_v2` method for distribution strategies and
        renamed the method `run` as it is no longer experimental.
