11
+
12
+ 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
15
+
16
+ `neulab/omnitab-large-128shot-finetuned-wtq-128shot` (based on BART architecture) is initialized with `neulab/omnitab-large-128shot` and fine-tuned on [WikiTableQuestions](https://huggingface.co/datasets/wikitablequestions) in the 128-shot setting.

18
+ ## Usage
19
+
20
+ ```python
21
+ from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
22
+ import pandas as pd
23
+
24
+ tokenizer = AutoTokenizer.from_pretrained("neulab/omnitab-large-128shot-finetuned-wtq-128shot")
25
+ model = AutoModelForSeq2SeqLM.from_pretrained("neulab/omnitab-large-128shot-finetuned-wtq-128shot")
26
+
27
+ data = {
28
+ "year": [1896, 1900, 1904, 2004, 2008, 2012],
29
+ "city": ["athens", "paris", "st. louis", "athens", "beijing", "london"]
30
+ }
31
+ table = pd.DataFrame.from_dict(data)
32
+
33
+ query = "In which year did beijing host the Olympic Games?"
34
+ encoding = tokenizer(table=table, query=query, return_tensors="pt")
35
+
36
+ outputs = model.generate(**encoding)
37
+
38
+ print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
39
+ # [' 2008']
40
+ ```
