Replaced "from_numpy" with "as_tensor" in docs. (#16587)
Summary:
In the warning box on https://pytorch.org/docs/stable/tensors.html#torch.Tensor.new_tensor it says:
> new_tensor() always copies data. [...] If you have a numpy array and want to avoid a copy, use **torch.from_numpy()**.
But then further up the page we have another warning box with the message:
> torch.tensor() always copies data. [...] If you have a numpy array and want to avoid a copy, use **torch.as_tensor()**.
Now I believe this is just a small oversight, since from_numpy is to be deprecated in favour of as_tensor. See for example https://github.com/pytorch/pytorch/issues/6885 and https://github.com/pytorch/pytorch/issues/8611. I suggest to just use **torch.as_tensor()** in both of the warning boxes.
