The overall norm is computed over all gradients together, as if they were concatenated into a single vector. Args: module: :class:`torch.nn.Module` to inspect. norm_type: The type of the used p-norm, cast to float if necessary. Can be ``'inf'`` for infinity norm. group_separator: The separator string used by the logger to group the gradients norms in their own subfolder instead of the logs one. Return: norms: The dictionary of p-norms of each parameter's gradient and a special entry for the total p-norm of the gradients viewed as a single vector. rzD`norm_type` must be a positive number or 'inf' (infinity norm).
