WebYour loss function is programmatically correct except for below: # the number of tokens is the sum of elements in mask num_tokens = int (torch.sum (mask).data [0]) When you do torch.sum it returns a 0-dimensional tensor and hence the warning that it can't be indexed. WebA torch.Tensor is a multi-dimensional matrix containing elements of a single data type. Data types Torch defines 10 tensor types with CPU and GPU variants which are as follows: [ 1] Sometimes referred to as binary16: uses 1 sign, 5 exponent, and 10 significand bits. Useful when precision is important at the expense of range. [ 2]
