Compute gradients for a FakeQuantWithMinMaxVars operation.

gradients A Tensor of type float32. Backpropagated gradients above the FakeQuantWithMinMaxVars operation.
inputs A Tensor of type float32. Values passed as inputs to the FakeQuantWithMinMaxVars operation. min, max: Quantization interval, scalar floats.
min A Tensor of type float32.
max A Tensor of type float32.
num_bits An optional int. Defaults to 8. The bitwidth of the quantization; between 2 and 8, inclusive.
narrow_range An optional bool. Defaults to False. Whether to quantize into 2^num_bits - 1 distinct values.
name A name for the operation (optional).
