WebDec 19, 2024 · Sparse Tensors are implemented in PyTorch. I tried to use a sparse Tensor, but it ends up with a segmentation fault. import torch from torch.autograd import Variable from torch.nn import functional as F # build sparse filter matrix i = torch.LongTensor ( [ [0, 1, 1], [2, 0, 2]]) v = torch.FloatTensor ( [3, 4, 5]) filter = Variable … WebMar 28, 2024 · However, you can achieve similar results using tensor==number and then the nonzero () function. For example: t = torch.Tensor ( [1, 2, 3]) print ( (t == 2).nonzero (as_tuple=True) [0]) This piece of code returns 1 [torch.LongTensor of size 1x1] Share Improve this answer Follow edited Feb 10, 2024 at 10:54 answered Dec 18, 2024 at 11:26
