deberta-v3-base-qa-en

This model is an extractive qa model. It's a fine-tuned version of deberta-v3-base 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/deberta-v3-base-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/deberta-v3-base-qa-en"
model = AutoModelForQuestionAnswering.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
