Img_ir variable img_ir requires_grad false
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). Witryna9 paź 2024 · I'm running into all sorts of inconsistencies in the interplay between .is_leaf, grad_fn, requires_grad, grad attributes of a tensor. for example: a = torch.ones(2,requires_grad=False); b = 2*a; b.requires_grad=True; print(b.is_leaf) #True.. here b is neither user-created nor does it have its requires_grad …

WitrynaIs True if gradients need to be computed for this Tensor, False otherwise. Note The fact that gradients need to be computed for a Tensor do not mean that the grad attribute will be populated, see is_leaf for more details.
