Usage

In Transformers

from transformers import AutoModelForQuestionAnswering, AutoTokenizer, pipeline
model_name = "Srini99/FYP_TamilQA"

model = AutoModelForQuestionAnswering.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

nlp = pipeline('question-answering', model=model_name, tokenizer=model_name)
QA_input = {
    'question': 'யாரால் பொங்கல் சிறப்பாகக் கொண்டாடப்படுகிறது?',
    'context': 'பொங்கல் என்பது தமிழர்களால் சிறப்பாகக் கொண்டாடப்படும் ஓர் அறுவடைப் பண்டிகை ஆகும்.'
}
res = nlp(QA_input)
