dequantize(_:scaleTensor:zeroPointTensor:dataType:name:)
Creates a dequantize operation and returns the result tensor.
Declaration
func dequantize(_ tensor: MPSGraphTensor, scaleTensor: MPSGraphTensor, zeroPointTensor: MPSGraphTensor, dataType: MPSDataType, name: String?) -> MPSGraphTensorParameters
- tensor:
Input tensor to be dequantized.
- scaleTensor:
The scale tensor with groups support.
- zeroPointTensor:
The bias tensor with groups support.
- dataType:
Float data type of the result tensor.
- name:
The name for the operation.
Return Value
A valid MPSGraphTensor array of datatype dataType.
Discussion
Convert the i8, u8, i4 or u4 tensor to a float tensor by applying a scale and bias transform:
result = scaleTensor(tensor - zeroPointTensor).
