This API can only run in dynamic graph mode, not static graph mode. Args: parameters (Iterable[paddle.Tensor]|paddle.Tensor): Tensors or a single Tensor that will be normalized gradients clip_value (float|int): maximum allowed value of the gradients. The gradients are clipped in the range :math:`\left[\text{-clip\_value}, \text{clip\_value}\right]` Example: .. code-block:: python >>> import paddle >>> x = paddle.uniform([10, 10], min=-10.0, max=10.0, dtype='float32') >>> clip_value = float(5.0) >>> linear = paddle.nn.Linear(in_features=10, out_features=10) >>> out = linear(x) >>> loss = paddle.mean(out) >>> loss.backward() >>> paddle.nn.utils.clip_grad_value_(linear.parameters(), clip_value) >>> sdg = paddle.optimizer.SGD(learning_rate=0.1, parameters=linear.parameters()) >>> sdg.step() z&this API can only run in dynamic mode.N)minmax) paddleZin_dynamic_mode RuntimeError isinstanceZTensorfloat enumerateZgradZclip_) parametersZ clip_value_pr a/var/www/html/Deteccion_Ine/venv/lib/python3.10/site-packages/paddle/nn/utils/clip_grad_value_.pyclip_grad_value_s  r)r__all__ZautogradZno_gradrr r r r s
