pub unsafe extern "C" fn nn_tensor_quantization_type(
    tensor: *mut NNTensor
) -> NNQuantizationType
Expand description

Returns the quantization type for the tensor.

@note This API was missing before version 2.4.32 and instead the quantization format is inferred as affine when scales and zeros are provided and per-tensor vs. per-channel is inferred based on scales/zeros being 1 or greater than 1.

@param tensor the tensor object used to query quantization type.

@returns @ref NNQuantizationType_None for tensors which do not provide quantization parameters. @returns @ref NNQuantizationType_Affine_PerTensor for tensors which provide quantization parameters which map globally to the tensor. @returns @ref NNQuantizationType_Affine_PerChannel for tensors which provide quantization parameters which map to each channel “C” of the tensor. @returns @ref NNQuantizationType_DFP for tensors which provide DFP parameters. Currently unsupported.
