How can I backpropagate the gradients across the comparison operator? deep-learning WebReturns true if this tensor resides in pinned memory. is_set_to (tensor) → bool ¶ Returns True if both tensors are pointing to the exact same memory (same storage, offset, size and stride). is_shared [source] ¶ Checks if tensor is in shared memory. This is always True for CUDA tensors. is_signed → bool ¶

WebIn PyTorch, the fill value of a sparse tensor cannot be specified explicitly and is assumed to be zero in general. However, there exists operations that may interpret the fill value differently. For instance, torch.sparse.softmax () computes the softmax with the assumption that the fill value is negative infinity. Sparse Compressed Tensors WebAug 2, 2024 · The difference is actually whether it becomes a python int or a Tensor again. With (x==y).sum (1) you get the overflow with tensors.
