Pytorch tensor int to float
Web2 days ago · 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) which produces a list of shape [N, 3] of type torch.int. that contains indices on which the condition was satisfied, N being the number of found objects. Now, I thought is was ... WebPyTorch has twelve different data types: [ 1] Sometimes referred to as binary16: uses 1 sign, 5 exponent, and 10 significand bits. Useful when precision is important. [ 2] Sometimes referred to as Brain Floating Point: use 1 sign, 8 exponent and 7 significand bits.
