# Module: dragnn_ops

### Module `dragnn_ops`

Defined in
[`tensorflow/dragnn/python/dragnn_ops.py`](https://github.com/tensorflow/models/blob/master/syntaxnet/dragnn/python/dragnn_ops.py).

Groups the DRAGNN TensorFlow ops in one module.

## Members

handle to a ComputeSession, advances based on the next oracle action.

[`advance_from_prediction(...)`](./dragnn_ops/advance_from_prediction.md): Given
a handle to a ComputeSession and a tensor of scores, advances the state.
