This is adapted from :func:`torch.nn.utils.clip_grad.clip_grad_norm_` and
2022-03-25 05:02:39 +00:00
added functionality to handle model parallel parameters.
Note:
the gradients are modified in place.
Args:
parameters (Iterable[:class:`torch.tensor`] or :class:`torch.tensor`):
An iterable of Tensors or a single Tensor that will have gradients normalized.
max_norm (Union[float, int]): Max norm of the gradients.
norm_type (Union[float, int, 'inf']): Type of the used p-norm. Can be ``'inf'`` for infinity norm.
Returns:
float: Total norm of the parameters.
