Compute gradients for a FakeQuantWithMinMaxVars operation.

Args:

• 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).

Returns:

A tuple of Tensor objects (backprops_wrt_input, backprop_wrt_min, backprop_wrt_max).

• backprops_wrt_input: A Tensor of type float32.
• backprop_wrt_min: A Tensor of type float32.
• backprop_wrt_max: A Tensor of type float32.
