# Expert-Specialized Fine-Tuning
Official Repo for paper [Let the Expert Stick to His Last: Expert-Specialized Fine-Tuning for Sparse Architectural Large Language Models](https://arxiv.org/abs/2407.01906) by
[Zihan Wang](https://zihanwang314.github.io), [Deli Chen](https://victorchen96.github.io/chendeli.io/), [Damai Dai](https://scholar.google.com.hk/citations?user=8b-ysf0NWVoC&hl=zh-CN), [Runxin Xu](https://runxinxu.github.io/aboutme/),

**ESFT** aims to efficiently customize Large Language Models (LLMs) with Mixture-of-Experts (MoE) architecture by adjusting only task-relevant parts, improving efficiency and performance while using fewer resources and storage.
## 📰 News
📅 **2024.9.20:** Glad to announce that ESFT has been accepted to the **EMNLP 2024 Main Conference**!
📅 **2024.8.11:** We now release the **ESFT training code**! ✨ You can now try it with your own models and dataset!
## 🚀 Quick Start
### Installation and Setup
```bash
git clone https://github.com/deepseek-ai/ESFT.git
cd esft
```
### Install required dependencies
```bash
pip install transformers torch safetensors accelerate
```
### Download necessary adapters
```bash
bash scripts/download_adapters.sh
```
## 🔧Key Scripts
1. **eval_multigpu.py**
This script evaluates the performance of the model on various datasets. See **scripts/eval.sh** for detailed configs and explanations.
**Usage:**
```bash
python eval_multigpu.py \
--eval_dataset=translation \
--base_model_path=deepseek-ai/ESFT-vanilla-lite \
--adapter_dir=all_models/adapters/token/translation \
--output_path=results/completions/token/translation.jsonl \
--openai_api_key=YOUR_OPENAI_API_KEY
```
2. **get_expert_scores.py**
This script calculates the scores for each expert based on the evaluation datasets.
**Usage:**
```bash
python scripts/expert/get_expert_scores.py \
--eval_dataset=translation \
--base_model_path=deepseek-ai/ESFT-vanilla-lite \
--output_dir=results/expert_scores/translation \
--n_sample_tokens=131072 \
--world_size=4 \
--gpus_per_rank=2
```
3. **generate_expert_config.py**
This script generates the configuration to convert a MoE model with only task-relevant tasks trained based on evaluation scores.
**Usage:**
```bash
python scripts/expert/generate_expert_config.py \
--eval_datasets=intent,summary,law,translation \
--expert_scores_dir=results/expert_scores \
--output_dir=results/expert_configs \
--score_function=token \
--top_p=0.2 # the scoring function and top_p are hyperparameters
```
4. **train.py** and **train_ep.py**
This script trains the model with the expert configuration generated by the previous script. The train_ep.py file uses expert parallel and has been optimized for multi-GPU training.
**Usage:**
```bash
python train.py \
--base_model_path=deepseek-ai/ESFT-vanilla-lite \
--expert_config=results/expert_configs/intent.json \
--train_dataset=intent \
--train_config=configs/base.yaml \
--output_dir=results/checkpoints/intent
torchrun --nproc-per-node=8 train_ep.py \
--base_model_path=deepseek-ai/ESFT-vanilla-lite \
--expert_config=results/expert_configs/translation.json \
--train_dataset=translation \
--train_config=configs/base.yaml \
--output_dir=results/checkpoints/translation
```
