The gradient of
[SparseFillEmptyRows](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/sparse-fill-empty-rows#classtensorflow_1_1ops_1_1_sparse_fill_empty_rows)
.

## Summary


Takes vectors reverse_index_map, shaped
`
[N]
`
, and grad_values, shaped
`
[N_full]
`
, where
`
N_full >= N
`
and copies data into either
`
d_values
`
or
`
d_default_value
`
. Here
`
d_values
`
is shaped
`
[N]
`
and
`
d_default_value
`
is a scalar.


d_values\[j\] = grad_values\[reverse_index_map\[j\]\] d_default_value = sum_{k : 0 .. N_full - 1} ( grad_values\[k\] \* 1{k not in reverse_index_map})


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- reverse_index_map: 1-D. The reverse index map from [SparseFillEmptyRows](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/sparse-fill-empty-rows#classtensorflow_1_1ops_1_1_sparse_fill_empty_rows) .
- grad_values: 1-D. The gradients from backprop.

Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` d_values: 1-D. The backprop into values.
- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` d_default_value: 0-D. The backprop into default_value.
