ValueError: max() arg is an empty sequence

[shanefeng123]

Hi,

Thank you for providing the implementation of dager.

I've tried to run your attack on my own dataset and I encounter an error at this line. The error is a ValueError: max() arg is an empty sequence error. Upon further investigation, predicted_sentences is an empty list.

The specific data sentence is the one below.

ɒya ध 560 331 shiveriyaiya 1782 hectare 1757 with [unused359] [unused615] 42 schoolhouse 277 ও 1868 176 [unused733] 201 [unused89] ！ ！ and 1724 251 terrific 306 [unused807] whereabouts iii gratitude iii does remain 37th presently!et! louisiana 1868 1878 1881 ？

Can you please try to see if you can reproduce this error? I used the bert-base-uncased model and a batch size of 1.

Thank you in advance.

Best,
Shane
