# TableGPT2-7B
|
||||
|
||||
## Model details
|
||||
|
||||
We developed and released TableGPT2-7B, a large-scale decoder specifically tailored for data-intensive tasks, with a focus on interpreting and analyzing tabular data. TableGPT2-7B is designed to bridge the gap between conventional LLM capabilities and the real-world demands of tabular/structured data tasks, such as those in business intelligence (BI), automated data-driven analysis, and application tasks tightly involving databases or data warehouses.
|
||||
|
||||
**Model Developers**
|
||||
|
||||
Zhejiang University
|
||||
|
||||
**Variations**
|
||||
|
||||
TableGPT2 is available in two configurations—7B and 72B parameters—both derived from the Qwen2.5 model family and optimized for handling structured data in tabular formats. Currently, we have released the 7B version to the public.
|
||||
|
||||
**Input**
|
||||
|
||||
TableGPT2-7B accepts both text and tabular data as input, with the tabular data structured as text in the format of a df.head() result.
|
||||
|
||||
**Output**
|
||||
|
||||
TableGPT2-7B produces text-based outputs, specifically optimized for coding tasks, data interpretation, and BI-focused question answering.
|
||||
|
||||
**Language**
|
||||
|
||||
Our model places a strong emphasis on Chinese corpora, and currently, queries in other languages may have limited support.
|
||||
|
||||
**Other Requirements**
|
||||
|
||||
We highly recommend exploring [our repository on GitHub](https://github.com/tablegpt/tablegpt-agent), where users can integrate this model into our agent workflow for enhanced performance.
|
||||
|
||||
**Model Architecture**
|
||||
|
||||
TableGPT2-7B is built upon the Qwen2.5 architecture and includes specialized encoding for tabular data. It features a unique semantic encoder designed to interpret tabular data, capturing insights from rows, columns, and entire tables. Continual Pretraining (CPT) and Supervised Fine-Tuning (SFT) have been applied to equip the model for real-world BI applications and complex query processing.
|
||||
|
||||
For now, the standalone decoder is open-sourced and fully functional without having to require assistance from the encoder. The encoder is currently under preparation, pending engineering considerations, primarily because we hope to provide a tighter integration with DeepSpeed and vLLM.

| | Training Data | Params | Context Length | Tokens | Tables |
|
||||
| ------------ | ------------------------------------------------ | ------ | -------------- | --------------------------------- | ------------- |
|
||||
| TableGPT2-7B | Multimodal data sources and BI-specific examples | 7B | 128K | 86B tokens CPT, 2.36M SFT samples | 593.8K tables |
|
||||
|
||||
**Status**
|
||||
|
||||
This model is static, trained on an offline dataset. Future versions may be released to enhance its performance on specialized tasks.
|
||||
|
||||
**QuickStart**
|
||||
|
||||
This code snippet demonstrates how to build a prompt with table information, and shows how to load the tokenizer, load the model, and generate content.
|
||||
|

> Note that you need `transformers>=4.37.0` to use `TableGPT2`:
|
||||
> ```sh
|

|
||||
|
||||
**Complex Usage Scenarios**
|
||||
|
||||
For complex usage scenarios, we provide a [tablegpt-agent]((https://github.com/tablegpt/tablegpt-agent)) toolkit to help you more conveniently handle various types of tabular inputs.
|
||||
|
||||
This agent is built on top of the `Langgraph` library and provides a user-friendly interface for interacting with `TableGPT2`.
|
||||
|
||||
|
||||
**Deployment**
|
||||
|
||||
For deployment, we recommend using vLLM.
|
||||
* **Install vLLM**: You can install vLLM by running the following command.
|
||||
```bash
|
||||
pip install "vllm>=0.5.5"
|
||||
```
|
||||
* **Model Deployment**: Use vLLM to deploy your model. For example, you can use the command to set up a server similar to openAI:
|
||||
```bash
|
||||
python -m vllm.entrypoints.openai.api_server --served-model-name TableGPT2-7B --model path/to/weights
|
||||
```
|
||||
Then you can access the Chat API by:
|
||||
|
||||
```bash
|
||||
curl http://localhost:8000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "TableGPT2-7B",
|
||||
"messages": [
|
||||
{"role": "system", "content": "You are a helpful assistant."},
|
||||
{"role": "user", "content": "Hey, who are you?"}
|
||||
]
|
||||
}'
|
||||
|
||||
```
|
||||

|
||||
**Research Paper**
|
||||
|
||||
TableGPT2-7B is introduced and validated in the paper "[TableGPT2: A Large Multimodal Model with Tabular Data Integration](https://arxiv.org/pdf/2411.02059)" available on arXiv.

|
||||
## Training Data
|
||||
|
||||
**Overview**
|
||||
|
||||
Training for TableGPT2-7B involved more than 593,800 curated tables, over 86 billion tokens for continual pretraining (CPT) and the construction of over 2.36 million high-quality query-table-output tuples for supervised fine-tuning. This extensive dataset aims to meet the rigorous demands of modern applications involving structured or tabular data.
|
||||
|
||||
**Data Freshness**
|
||||
|
||||
The training data has a cutoff of October 2024.
|
||||
|
||||
## Evaluation Results
|
||||
|
||||
Evaluation has shown that TableGPT2-7B performs consistently well across benchmarks for tabular comprehension, code generation, and structured data reasoning, achieving a **35.20%** performance increase over comparable models on standard benchmarks and **49.32%** on BI-focused assessments. The RealTabBench benchmark further demonstrated the model’s robustness in handling unconventional tables and complex queries. Below, we present the results on public table-related benchmarks.

Args:

Returns:

Note: this approach may not work if your application doesn't have sufficient free CPU memory and

you may need to use the offline approach using the ``zero_to_fp32.py`` script that is saved with

the checkpoint.

A typical usage might be ::

# do the training and checkpoint saving

|

model.load_state_dict(state_dict)
|
||||
# submit to model hub or save the model to share with others
|
||||
|
||||
In this example the ``model`` will no longer be usable in the deepspeed context of the same
|
||||
application. i.e. you will need to re-initialize the deepspeed engine, since

||||
``model.load_state_dict(state_dict)`` will remove all the deepspeed magic from it.

If you want it all done for you, use ``load_state_dict_from_zero_checkpoint`` instead.
