Model description

This model is based on facebook/bart-large and was finetuned on SQuAD2.0. The corresponding papers you can found here (model) and here (data).

How to use

from transformers.pipelines import pipeline

model_name = "phiyodr/bart-large-finetuned-squad2"
nlp = pipeline('question-answering', model=model_name, tokenizer=model_name)
inputs = {
    'question': 'What discipline did Winkelmann create?',
    'context': 'Johann Joachim Winckelmann was a German art historian and archaeologist. He was a pioneering Hellenist who first articulated the difference between Greek, Greco-Roman and Roman art.
