# TAPEX (base-sized model)
|
10 |
+
|
11 |
+
TAPEX was proposed in [TAPEX: Table Pre-training via Learning a Neural SQL Executor](https://arxiv.org/abs/2107.07653) by Qian Liu, Bei Chen, Jiaqi Guo, Morteza Ziyadi, Zeqi Lin, Weizhu Chen, Jian-Guang Lou. The original repo can be found [here](https://github.com/microsoft/Table-Pretraining).
|
12 |
+
|
13 |
+
## Model description
|
14 |
+
|
15 |
+
TAPEX (**Ta**ble **P**re-training via **Ex**ecution) is a conceptually simple and empirically powerful pre-training approach to empower existing models with *table reasoning* skills. TAPEX realizes table pre-training by learning a neural SQL executor over a synthetic corpus, which is obtained by automatically synthesizing executable SQL queries.
|
16 |
+
|
17 |
+
TAPEX is based on the BART architecture, the transformer encoder-encoder (seq2seq) model with a bidirectional (BERT-like) encoder and an autoregressive (GPT-like) decoder.
|
18 |
+
|
19 |
+
This model is the `tapex-base` model fine-tuned on the [WikiTableQuestions](https://huggingface.co/datasets/wikitablequestions) dataset.
|
20 |
+
|
21 |
+
## Intended Uses
|
22 |
+
|
23 |
+
You can use the model for table question answering on *complex* questions. Some **solveable** questions are shown below (corresponding tables now shown):

### How to Use
|
35 |
+
|
36 |
+
Here is how to use this model in transformers:
|
37 |
+
|
38 |
+
```python
|
39 |
+
from transformers import TapexTokenizer, BartForConditionalGeneration
|
40 |
+
import pandas as pd
|
41 |
+
|
42 |
+
tokenizer = TapexTokenizer.from_pretrained("microsoft/tapex-base-finetuned-wtq")
|
43 |
+
model = BartForConditionalGeneration.from_pretrained("microsoft/tapex-base-finetuned-wtq")
|
44 |
+
|
45 |
+
data = {
|
46 |
+
"year": [1896, 1900, 1904, 2004, 2008, 2012],
|
47 |
+
"city": ["athens", "paris", "st. louis", "athens", "beijing", "london"]
|
48 |
+
}
|
49 |
+
table = pd.DataFrame.from_dict(data)
|
50 |
+
|
51 |
+
# tapex accepts uncased input since it is pre-trained on the uncased corpus
|
52 |
+
query = "In which year did beijing host the Olympic Games?"
|
53 |
+
encoding = tokenizer(table=table, query=query, return_tensors="pt")
|
54 |
+
|
55 |
+
outputs = model.generate(**encoding)
|
56 |
+
|
57 |
+
print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
|
58 |
+
# [' 2008.0']
|
59 |
+
```
|
60 |
+
