Linear
class torch.ao.nn.qat.Linear(in_features, out_features, bias=True, qconfig=None, device=None, dtype=None)
A linear module attached with FakeQuantize modules for weight, used
   for quantization aware training.
We adopt the same interface as torch.nn.Linear, please see
   https://pytorch.org/docs/stable/nn.html#torch.nn.Linear for
   documentation.
Similar to torch.nn.Linear, with FakeQuantize modules initialized
   to default.
Variables:
      weight (torch.Tensor) -- fake quant module for weight
classmethod from_float(mod)
  Create a qat module from a float module or qparams_dict Args:
  *mod* a float module, either produced by torch.ao.quantization
  utilities or directly from user
