Description
This PR adds a
requires_gradproperty to Paddle Tensors to provide compatibility and improve user experience.What's added:
requires_gradproperty to Tensor class across all execution modes (dynamic graph, static graph, and PIR)requires_gradis the inverse ofstop_gradient(requires_grad=True means stop_gradient=False)Key features:
not self.stop_gradient, allowing users to check if gradient computation is enabledself.stop_gradient = not valueFiles modified:
