Pytorch pad sequence to length

WebMay 20, 2024 · On X-NLI, shortest sequences are 10 tokens long, if you provide a 128 tokens length, you will add 118 pad tokens to those 10 tokens sequences, and then perform computations over those 118 noisy tokens. Worst, as written in the original BERT repo README, “…attention is quadratic to the sequence length. WebIn torchscript mode padding as single int is not supported, use a sequence of length 1: [padding, ]. fill ( number or tuple) – Pixel fill value for constant fill. Default is 0. If a tuple of length 3, it is used to fill R, G, B channels respectively. This value is only used when the padding_mode is constant.
