WebA torch.dtype is an object that represents the data type of a torch.Tensor. PyTorch 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.
