torch.Tensor.resize_as_
Tensor.resize_as_(tensor, memory_format=torch.contiguous_format) -> Tensor
Resizes the "self" tensor to be the same size as the specified
   "tensor". This is equivalent to "self.resize_(tensor.size())".
Parameters:
      memory_format ("torch.memory_format", optional) -- the
      desired memory format of Tensor. Default:
      "torch.contiguous_format". Note that memory format of "self" is
      going to be unaffected if "self.size()" matches "tensor.size()".
