I have this error. It seems the size of idf_dict_ref and idf_dict_hyp is not the same?

[vejvarm]

Are your refs and hyps lists the same length when you input it to word_mover_score(refs, hyps, ...)?

[andyweizhao]

Can you check the format of your input texts? The code supports two evaluation setups: single-ref and multi-ref.
For single-ref, refs and hyps lists have the same length, as each system output is paired with only one reference.
