Hi, thank you for your great work!

I encountered the following error in predictor.py` when trying to test BertAbs model.

python train.py -task abs -mode test -test_from ../models/abs/model_step_8000.pt -batch_size 3000 -test_batch_size 500 -bert_data_path ../bert_data/bert.pt_data -log_file ../logs/test_abs -model_path ../models/abs -sep_optim true -use_interval true -visible_gpus 0 -max_pos 512 -max_length 200 -alpha 0.95 -min_length 50 -result_path ../logs/abs

[alive_seq.index_select(0, select_indices),

Below is a shape and contents of select_indices and alive_seq. FloatTensor cannot be used for the argument of .index_select() (only IntTensor or LongTensor is suitable). How should I fix it? Thank you!

select_indices.shape: torch.Size([30])

topk_beam_index = topk_ids.div(vocab_size)

        topk_beam_index = topk_ids // vocab_size

请问解决了吗？我也遇到了这个问题
