Compute gradients for a
[FakeQuantWithMinMaxVars](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/fake-quant-with-min-max-vars#classtensorflow_1_1ops_1_1_fake_quant_with_min_max_vars)
operation.

## Summary


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- gradients: Backpropagated gradients above the [FakeQuantWithMinMaxVars](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/fake-quant-with-min-max-vars#classtensorflow_1_1ops_1_1_fake_quant_with_min_max_vars) operation.
- inputs: Values passed as inputs to the [FakeQuantWithMinMaxVars](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/fake-quant-with-min-max-vars#classtensorflow_1_1ops_1_1_fake_quant_with_min_max_vars) operation. min, max: Quantization interval, scalar floats.

`
):

- num_bits: The bitwidth of the quantization; between 2 and 8, inclusive.
- narrow_range: Whether to quantize into 2\^num_bits - 1 distinct values.
