IndexError on Evaluator (Token classification)

Hi all,

I’m trying to evaluate NER datasets. I can evaluate the performance of CoNLL-2003 English and CoNLL-2002 Spanish. But I found the index error when I evaluated the performance on CoNLL-2002 Dutch.

Here are my codes:

from evaluate import evaluator
from datasets import load_dataset
task_evaluator = evaluator("token-classification")

data = load_dataset("conll2002",'nl',split="test")

results = task_evaluator.compute(
    model_or_pipeline="xlm-roberta-large-finetuned-conll03-english",
    data=data,
    metric="seqeval",
)
print(results)

And here my errors:

Cell In [5], line 1
----> 1 results = task_evaluator.compute(
      2     model_or_pipeline="xlm-roberta-large-finetuned-conll03-english",
      3     data=data,
      4     metric="seqeval",
      5 )
      6 print(results)

    252 predictions, perf_results = self.call_pipeline(pipe, pipe_inputs)
--> 253 predictions = self.predictions_processor(predictions, data[input_column], join_by)
    254 metric_inputs.update(predictions)
    256 # Compute metrics from references and predictions

    123 for word_offset in words_offsets:
    124     # for each word, we may keep only the predicted label for the first token, discard the others
--> 125     while prediction[token_index]["start"] < word_offset[0]:
    126         token_index += 1
    128     if prediction[token_index]["start"] > word_offset[0]:  # bad indexing
