Expand description

Returns the array of quantization zero-points, and optionally the number of zero-points in the array. The length will either be 0, 1, or equal to the number of channels in an NHWC/NCHW tensor.

The channel axis can be queried using @ref nn_model_layer_axis().

If no quantization parameters are available then n_zeros will be 0. If the tensor is quantized using full tensor quantization n_zeros will be 1. If the tensor is quantized using per-channel quantization n_zeros will be C which will equal the channel dimension of the tensor. For an NHWC tensor it would equal shape[3].
