lmqg/t5-base-squad-ae 的模型卡片

该模型是对 t5-base 进行微调得到的,用于在 lmqg/qg_squad (数据集名称:default)上进行答案提取任务。通过 lmqg 此方法。

概述

使用方法

from lmqg import TransformersQG

# initialize model
model = TransformersQG(language="en", model="lmqg/t5-base-squad-ae")

# model prediction
answers = model.generate_a("William Turner was an English painter who specialised in watercolour landscapes")
  • 使用 transformers
from transformers import pipeline

pipe = pipeline("text2text-generation", "lmqg/t5-base-squad-ae")
output = pipe("extract answers: <hl> Beyonce further expanded her acting career, starring as blues singer Etta James in the 2008 musical biopic, Cadillac Records. <hl> Her performance in the film received praise from critics, and she garnered several nominations for her portrayal of James, including a Satellite Award nomination for Best Supporting Actress, and a NAACP Image Award nomination for Outstanding Supporting Actress.")
