# OmniTab
|
||
|
|
||
|
OmniTab is a table-based QA model proposed in [OmniTab: Pretraining with Natural and Synthetic Data for Few-shot Table-based Question Answering](https://arxiv.org/pdf/2207.03637.pdf). The original Github repository is [https://github.com/jzbjyb/OmniTab](https://github.com/jzbjyb/OmniTab).

|
|
||
|
## Description
|
||
|
|
||
|
`neulab/omnitab-large-finetuned-wtq` (based on BART architecture) is initialized with `microsoft/tapex-large`, continuously pretrained on natural and synthetic data, and fine-tuned on [WikiTableQuestions](https://huggingface.co/datasets/wikitablequestions).
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
```python
|
||
|
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
|
||
|
import pandas as pd
|
||
|
|
||
|
tokenizer = AutoTokenizer.from_pretrained("neulab/omnitab-large-finetuned-wtq")
|
||
|
model = AutoModelForSeq2SeqLM.from_pretrained("neulab/omnitab-large-finetuned-wtq")
|
||
|
|
||
|
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']
|
||
|
```
