Usage in Transformers 🤗

Model checkpoints are available for usage in PyTorch. They can be used directly with pipelines as:

from transformers import pipelines

qa = pipeline('question-answering', model='anakin87/electra-italian-xxl-cased-squad-it')
qa(question="Qual è il soprannome di Vasco Rossi?", context="Vasco Rossi, noto anche semplicemente come Vasco e in passato con l'appellativo Blasco (Zocca, 7 febbraio 1952), è un cantautore italiano")
>>> {'score': 0.93, 'start': 80, 'end': 86, 'answer': 'Blasco'}

Usage in Haystack 🚀🚀🚀

With the Haystack NLP framework, you can use this model and create a scalable Question Answering system that works across millions of documents.
