Img_ir variable img_ir requires_grad false

Witryna每个变量都有两个标志： requires_grad 和 volatile 。 它们都允许从梯度计算中精细地排除子图，并可以提高效率。 requires_grad 如果有一个单一的输入操作需要梯度，它的输出也需要梯度。 相反，只有所有输入都不需要梯度，输出才不需要。 如果其中所有的变量都不需要梯度进行，后向计算不会在子图中执行。 Witryna1 cze 2024 · For example if you have a non-leaf tensor, setting it to True using self.requires_grad=True will produce an error, but not when you do requires_grad_ (True). Both perform some error checking, such as verifying that the tensor is a leaf, before calling into the same set_requires_grad function (implemented in cpp).
