Struct QuantizedTensor

Source

pub struct QuantizedTensor { /* private fields */ }

Expand description

A tensor stored in quantized (integer) representation.

The real value is recovered by x = (q - zero_point) * scale.

scale and zero_point are vectors whose length equals:

1 for PerTensor
shape[axis] for PerChannel(axis)
