torch.nn.utils.clip_grad_value_¶

torch.nn.utils.clip_grad_value_(parameters: Union[torch.Tensor, Iterable[torch.Tensor]], clip_value: float) → None[source]¶

Clips gradient of an iterable of parameters at specified value.

Gradients are modified in-place.

Parameters

• parameters (Iterable[Tensor] or Tensor) – an iterable of Tensors or a single Tensor that will have gradients normalized

• clip_value (float or int) – maximum allowed value of the gradients. The gradients are clipped in the range $\left[\text{-clip\_value}, \text{clip\_value}\right]$
