      question: What is a person called is practicing heresy?, context: Heresy
      is any provocative belief or theory that is strongly at variance with
      established beliefs or customs. A heretic is a proponent of such claims or
      beliefs. Heresy is distinct from both apostasy, which is the explicit
      renunciation of one's religion, principles or cause, and blasphemy, which
      is an impious utterance or action concerning God or sacred things.

Model Card of `lmqg/t5-large-tweetqa-qa`

This model is fine-tuned version of t5-large for question answering task on the lmqg/qg_tweetqa (dataset_name: default) via lmqg.

Overview

Language model: t5-large
Language: en
Training data: lmqg/qg_tweetqa (default)
Online Demo: https://autoqg.net/
Repository: https://github.com/asahi417/lm-question-generation
Paper: https://arxiv.org/abs/2210.03992

Usage

With lmqg

from lmqg import TransformersQG

# initialize model
model = TransformersQG(language="en", model="lmqg/t5-large-tweetqa-qa")

# model prediction
answers = model.answer_q(list_question="What is a person called is practicing heresy?", list_context=" Heresy is any provocative belief or theory that is strongly at variance with established beliefs or customs. A heretic is a proponent of such claims or beliefs. Heresy is distinct from both apostasy, which is the explicit renunciation of one's religion, principles or cause, and blasphemy, which is an impious utterance or action concerning God or sacred things.")

With transformers

from transformers import pipeline

pipe = pipeline("text2text-generation", "lmqg/t5-large-tweetqa-qa")
output = pipe("question: What is a person called is practicing heresy?, context: Heresy is any provocative belief or theory that is strongly at variance with established beliefs or customs. A heretic is a proponent of such claims or beliefs. Heresy is distinct from both apostasy, which is the explicit renunciation of one's religion, principles or cause, and blasphemy, which is an impious utterance or action concerning God or sacred things.")
