I don't see you do truncate when the sequence longer than 512 lengths?

We know that when loading pretrained bert, max_seqence=512, but when you are dealing with the sentences from data set, each sentence is padding based on the longest sentence of the batch, but I don't see you do truncate when the sequence longer than 512 lengths?

Thanks

I wrote a Bert+CRF model, which has 92.29% f1 on test data, a little higher performance than yours, but a little bit worse than the paper's 92.4 %, why?
