Bad alignement line exists. Please check file!


I use fast_ Align generates alignment files.

Pretreatment increase --train_align --valid_align

Complete command:
onmt_preprocess -src_seq_length 260 -tgt_seq_length 260 -filter_valid -train_align train_align.txt -valid_align valid_align.txt -train_src tgt-train.txt -train_tgt src-train.txt -tgt-val.txt -valid_tgt src-val.txt -save_data pretreatment/demo -overwrite

But get wrong:

I don’t know where the problem is. Check that there are no blank lines in the file.
Asking for help.

You probably have a blank alignment line.

Thank you for your help. My problem has been solved.
