WebTorch defines 10 tensor types with CPU and GPU variants which are as follows: Sometimes referred to as binary16: uses 1 sign, 5 exponent, and 10 significand bits. Useful when precision is important at the expense of range. Sometimes referred to as Brain Floating Point: uses 1 sign, 8 exponent, and 7 significand bits. Webtorch. split (tensor, split_size_or_sections, dim=0)[source] Splits the tensor into chunks. Each chunk is a view of the original tensor. If split_size_or_sections is an integer type, then tensor will be split into equally sized chunks (if possible).
