Fast usage with pipelines:

from transformers import pipeline

qa_pipeline = pipeline(

    'context': "Manuel Romero has been working very hard in the repository hugginface/transformers lately",
    'question': "How has been working Manuel Romero lately?"


# Output: {'answer': 'very hard in the repository hugginface/transformers',
