Pytorch label to tensor
Web2 days ago · I'm trying to find an elegant way of getting a tensor, containing a list of specific subtensors in pytorch. Let's say I have a torch tensor x of size [B, W, H, C]. I check a kind of threshold condition on the channels, which gives me a tensor cond of size [B, W, H] filled with 0s and 1s. I employ. indices = torch.nonzero(cond) WebDec 16, 2024 · I want to create a label tensor of 128 batch size using the first value from each shape tensor so that label tensor consist of 14 values of index 0 , 16 values of index …
