TableLlama
Towards Open Large Generalist Models for Tables

Figure 1: An overview of TableInstruct and TableLlama. TableInstruct includes a wide variety of realistic tables and tasks with instructions. We make the first step towards developing open-source generalist models for tables with TableInstruct and TableLlama.

Figure 2: Illustration of three exemplary tasks: (a) Column type annotation. This task is to annotate the selected column with the correct semantic types. (b) Row population. This task is to populate rows given table metadata and partial row entities. (c) Hierarchical table QA. For subfigures (a) and (b), we mark candidates with red color in the "task instruction" part. The candidate set size can be hundreds to thousands in TableInstruct.

Datasets and Models

Our dataset and models are all available at Huggingface.

🤗 TableInstruct Dataset

🤗 TableLlama-7B

The model is fine-tuned with the TableInstruct dataset using LongLoRA (7B), fully fine-tuning version as the base model, which replaces the vanilla attention mechanism of the original Llama-2 (7B) with shift short attention. The training takes 9 days on a 48 80*A100 cluster. Check out our paper for more details.

TableInstruct includes a comprehensive table-based instruction tuning dataset that covers a variety of real-world tables and realistic tasks. We include 14 datasets of 11 tasks in total.

The model is evaluated on 8 in-domain datasets of 8 tasks and 6 out-of-domain datasets of 4 tasks.

Introduction

We introduce TableLlama and TableInstruct: the FIRST open-source generalist LLM and instruction tuning dataset for tables. The TableLlama model is trained on TableInstruct Dataset, a meticulously curated instruction tuning dataset for tables. TableLlama is tuned on 2.6 million table-based task data, and can handle up to 8K context!

Installation

Clone this repository and install the required packages:

git clone https://github.com/OSU-NLP-Group/TableLlama.git
cd TableLlama
pip install -r requirements.txt
pip install flash-attn --no-build-isolation

Training and Inference

Fine-tuning

To train the 7B model, run:

torchrun --nproc_per_node=8 supervised_fine_tune.py  \
        --model_name_or_path $MODEL_DIR \
        --bf16 True \

Addressing OOM To train the 7B model with super large data size, if you encounter OOM issue, we provide code for streaming. You can run:

torchrun --nproc_per_node=8 supervised_fine_tune_stream.py  \
        --model_name_or_path $MODEL_DIR \
        --bf16 True \
        --output_dir $OUTPUT_DIR  \

Inference

python3 inference_rel_extraction_col_type.py  \
        --base_model $MODEL_DIR \
        --context_size 8192 \
        --max_gen_len 128 \
        --flash_attn True \
        --input_data_file  /test_data/test_col_type.json \
        --output_data_file $OUTPUT_DIR/col_type_pred.json

Evaluation

The folder eval_scripts includes evaluation scripts for all the in-domain test sets. To run the script, take HiTab (hierarchical table QA task) as an example:

cd eval_scripts
python evaluate_hitab.py --file_pred $OUTPUT_DIR/hitab_pred.json

Prompt Format

Below is an instruction that describes a task, paired with an input that provides further context. Write a response that
appropriately completes the request.

### Instruction:
{instruction}

### Input:
{input}

### Question:
{question}

### Response:

• The instruction is designed to point out the task and give a detailed task description.
• The input is designed to provide the information about the table. We concatenate table metadata (if any) such as the Wikipedia page title, section title and table caption with the serialized table as table input. We use '[TLE]' to represent the beginning of the table metadata, and use '[TAB]' to represent the beginning of the serialized table.
• The question is to accommodate all the information the model needs to complete the task and prompt the model to generate an answer.
• Task prompts examples (For more example prompts for other tasks, please refer to Appendix E in our paper.)

Note:

• If you directly use our model for inference on your data, please make sure you organize the data in the same way as the examples shown above and in our paper Appendix. The performance will vary significantly along with the prompts.
