About the prediction file

[WildLight]

Hello, I use the checkpoint model and prediction file you provided. The following instructions are executed:
--do_predict
--output_dir
./output
--predict_file
"./data/paraphrase_selection_dev.nq.bbase.qp_mp.nopp.title.json"
--checkpoint
"./checkpoint/nq-base.PT"
--predict_batch_size
72
--threads
80
--n_paragraphs
100
--verbose
--prefix
test_
--pad_question
--max_question_length
0
--max_passage_length
240
--predict_batch_size
72
--test_M
5
--bert_name
bert-base-uncased

But I get the following error.

This is because in the feature's file the 'positive_input_ids' is 'None'.

Could you tell me how I can solve this mistake?
Thanks!
