    Replaces specified modules with dynamic weight-only quantized versions and output the quantized model.

    For simplest usage provide `dtype` argument that can be float16 or qint8. Weight-only quantization
    by default is performed for layers with large weights size - i.e. Linear and RNN variants.

    Fine grained control is possible with `qconfig` and `mapping` that act similarly to `quantize()`.
    If `qconfig` is provided, the `dtype` argument is ignored.

              configuration, qconfig applies to all submodules of a given

              submodule already has qconfig attribute). Entries in the dictionary
              need to be QConfig instances.

            - A set of types and/or submodule names to apply dynamic quantization to,
              in which case the `dtype` argument is used to specify the bit-width

        inplace: carry out model transformations in-place, the original module is mutated
