neulab/omnitab-large-1024shot-finetuned-wtq-1024shot (based on BART architecture) is initialized with neulab/omnitab-large-1024shot and fine-tuned on WikiTableQuestions in the 1024-shot setting.

Usage

python

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
import pandas as pd

tokenizer = AutoTokenizer.from_pretrained("neulab/omnitab-large-1024shot-finetuned-wtq-1024shot")
model = AutoModelForSeq2SeqLM.from_pretrained("neulab/omnitab-large-1024shot-finetuned-wtq-1024shot")

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']
