  - text: Which name is also used to describe the Amazon rainforest in English?
    context: >-
      The Amazon rainforest (Portuguese: Floresta Amazônica or Amazônia;
      Spanish: Selva Amazónica, Amazonía or usually Amazonia; French: Forêt
      amazonienne; Dutch: Amazoneregenwoud), also known in English as Amazonia
      or the Amazon Jungle, is a moist broadleaf forest that covers most of the
      Amazon basin of South America. This basin encompasses 7,000,000 square
      kilometres (2,700,000 sq mi), of which 5,500,000 square kilometres
      (2,100,000 sq mi) are covered by the rainforest. This region includes
      territory belonging to nine nations. The majority of the forest is
      contained within Brazil, with 60% of the rainforest, followed by Peru with
      13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador,
      Bolivia, Guyana, Suriname and French Guiana. States or departments in four
      nations contain "Amazonas" in their names. The Amazon represents over half
      of the planet's remaining rainforests, and comprises the largest and most
      biodiverse tract of tropical rainforest in the world, with an estimated
      390 billion individual trees divided into 16,000 species.

RoBERTa-base fine-tuned on SQuAD v1

This model was fine-tuned from the HuggingFace RoBERTa base checkpoint on SQuAD1.1. This model is case-sensitive: it makes a difference between english and English.

## Example Usage


```python
from transformers import pipeline

qa_pipeline = pipeline(
  "question-answering",
  model="csarron/roberta-base-squad-v1",
  tokenizer="csarron/roberta-base-squad-v1"
)

predictions = qa_pipeline({
  'context': "The game was played on February 7, 2016 at Levi's Stadium in the San Francisco Bay Area at Santa Clara, California.",
  'question': "What day was the game played on?"
})

print(predictions)
# output:
# {'score': 0.8625259399414062, 'start': 23, 'end': 39, 'answer': 'February 7, 2016'}
