dequantize(_:scaleTensor:zeroPoint:dataType:axis:name:)

Declaration

func dequantize(_ tensor: MPSGraphTensor, scaleTensor: MPSGraphTensor, zeroPoint: Double, dataType: MPSDataType, axis: Int, name: String?) -> MPSGraphTensor

Parameters

• tensor:

  Input tensor to be dequantized

• scaleTensor:

  Scale scalar or 1D Tensor parameter with size == tensor.shape[axis]

• zeroPoint:

  Bias scalar parameter (converted to dataType of tensor)

• dataType:

  Float data type of the result tensor.

• axis:

  Axis on which the scale 1D value is being broadcasted

• name:

  The name for the operation.

Return Value

A valid MPSGraphTensor array of datatype dataType

Discussion

Convert the i8 or u8 tensor to a float tensor by applying a scale + bias transform: result = scaleTensor(tensor - zeroPoint)
