# electra-base for Extractive QA |
|
|
|
## Overview |
|
**Language model:** electra-base |
|
**Language:** English |
|
**Downstream-task:** Extractive QA |
|
**Training data:** SQuAD 2.0 |
|
**Eval data:** SQuAD 2.0 |
|
**Code:** See [an example extractive QA pipeline built with Haystack](https://haystack.deepset.ai/tutorials/34_extractive_qa_pipeline) |
|
**Infrastructure**: 1x Tesla v100 |
|
|
|

## Usage |
|
|
|
### In Haystack |
|
Haystack is an AI orchestration framework to build customizable, production-ready LLM applications. You can use this model in Haystack to do extractive question answering on documents. |
|
To load and run the model with [Haystack](https://github.com/deepset-ai/haystack/): |
|
```python |
|
# After running pip install haystack-ai "transformers[torch,sentencepiece]" |
|
|
|
from haystack import Document |
|
from haystack.components.readers import ExtractiveReader |
|
|
|
docs = [ |
|
Document(content="Python is a popular programming language"), |
|
Document(content="python ist eine beliebte Programmiersprache"), |
|
] |
|
|
|
reader = ExtractiveReader(model="deepset/roberta-base-squad2") |
|
reader.warm_up() |
|
|
|
question = "What is a popular programming language?" |
|
result = reader.run(query=question, documents=docs) |
|
# {'answers': [ExtractedAnswer(query='What is a popular programming language?', score=0.5740374326705933, data='python', document=Document(id=..., content: '...'), context=None, document_offset=ExtractedAnswer.Span(start=0, end=6),...)]} |
|
``` |
|
For a complete example with an extractive question answering pipeline that scales over many documents, check out the [corresponding Haystack tutorial](https://haystack.deepset.ai/tutorials/34_extractive_qa_pipeline). |
|
|
|
### In Transformers |
|
```python |
|
from transformers import AutoModelForQuestionAnswering, AutoTokenizer, pipeline |
|
|
|
model_name = "deepset/roberta-base-squad2" |
|
|
|
# a) Get predictions |
|
nlp = pipeline('question-answering', model=model_name, tokenizer=model_name) |
|
QA_input = { |
|
'question': 'Why is model conversion important?', |
|
'context': 'The option to convert models between FARM and transformers gives freedom to the user and let people easily switch between frameworks.' |
|
} |
|
res = nlp(QA_input) |
|
|
|
# b) Load model & tokenizer |
|
model = AutoModelForQuestionAnswering.from_pretrained(model_name) |
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
``` |
