all-MiniLM-L12-v2-qa-en
This model is an extractive qa model. It's a fine-tuned version of all-MiniLM-L12-v2 on the following datasets: squad_v2, LLukas22/nq-simplified.
Usage
You can use the model like this:
from transformers import pipeline
#Make predictions
model_name = "LLukas22/all-MiniLM-L12-v2-qa-en"
nlp = pipeline('question-answering', model=model_name, tokenizer=model_name)
QA_input = {
"question": "What's my name?",
"context": "My name is Clara and I live in Berkeley."
}
result = nlp(QA_input)
print(result)
Alternatively you can load the model and tokenizer on their own:
from transformers import AutoModelForQuestionAnswering, AutoTokenizer
#Make predictions
model_name = "LLukas22/all-MiniLM-L12-v2-qa-en"
model = AutoModelForQuestionAnswering.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
