模型描述

neulab/omnitab-large（基于BART架构）以microsoft/tapex-large为初始模型，并在自然数据和合成数据上进行持续预训练。

模型信息

💻 使用示例

基础用法

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
import pandas as pd

tokenizer = AutoTokenizer.from_pretrained("neulab/omnitab-large")
model = AutoModelForSeq2SeqLM.from_pretrained("neulab/omnitab-large")

data = {
    "year": [1896, 1900, 1904, 2004, 2008, 2012],
    "city": ["athens", "paris", "st. louis", "athens", "beijing", "london"]
}
table = pd.DataFrame.from_dict(data)

query = "In which year did beijing host the Olympic Games?"
encoding = tokenizer(table=table, query=query, return_tensors="pt")

outputs = model.generate(**encoding)

print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
# [' 2008']
