Web30 Aug 2024 · I have a multi-dimensional index b and want to use it to select a single cell in a. If b wasn't a tensor, I could do: a[1,1,1,1] Which returns the correct cell, but: a[b] Doesn't work, because it just selects a[1] four times. How can I do this?

WebUnlike nontensor approaches, the dimensionality in the tensor approach can be eliminated. Thus, EDS is defined as the ratio of the Euclidean distance (d S, S ′) between the measured and predicted stress tensors to the Euclidean distance (d S, O) between the measured stress tensor and origin (in a two-dimensional (2D) space as shown in Fig. 2): (9) EDS S, S ′ = d S, … Web29 Oct 2024 · The same pattern holds for tensor[indexes] and tensor.index_select(0, indexes).This device pinning carries the same performance and portability risks as noted above. Replace Tensor Subscripting With masked_select and index_select. Subscript-based masking and indexing will always pin the tracing device into generated TorchScript.
Web8 May 2024 · I tried using tensor.gather and tensor.index_select but couldn’t get either to work. Intuitively I feel there must a better way of doing this. This is the code I have: labels = [] for label, idx in zip (preds.permute (2, 0, 1), best_model_idx_per_label): labels.append (label [idx]) torch.stack (labels) Would be grateful for any help.
