请问有人遇到这个问题吗？
在解码的时候出现的问题，select_indices应该是整数类型的，但是debug发现是float，将其select_indices转为long型后，运行就一直卡住了，不出测试结果

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
