## Setup (one-time)

```bash
# 1. Setup conda env (installs torch, transformers, trl, vllm, pyserini, etc.)
cd /home/datht/mats-sql-tist
bash scripts/setup_env_gf_henry.sh

# 2. Install alignment-handbook (custom ORPO)
source /home/datht/anaconda3/etc/profile.d/conda.sh
conda activate mats
cd /home/datht/mats-sql-tist/alignment-handbook
pip install -e .
```

---

## Base LLaMA Models (for retraining)

The recipe YAMLs reference `/home/datht/huggingface/meta-llama/Llama-3.2-{1B,3B}-Instruct`.
Download them from HuggingFace if not already present:

```bash
conda activate mats
python -c "
from huggingface_hub import snapshot_download
# LLaMA 3.2 3B (Planner, Selector)
snapshot_download('meta-llama/Llama-3.2-3B-Instruct',
                  local_dir='/home/datht/huggingface/meta-llama/Llama-3.2-3B-Instruct')
# LLaMA 3.2 1B (Validator, Fixer)
snapshot_download('meta-llama/Llama-3.2-1B-Instruct',
                  local_dir='/home/datht/huggingface/meta-llama/Llama-3.2-1B-Instruct')
"
```

## Running Experiments

### Step 1: Start BM25 API (for schema retrieval during SFT data build)
```bash
conda activate mats
cd /home/datht/mats-sql-tist
python db_content_retrieval/lsh_api.py --port 8005 &
```

### Step 2: Build SFT training data (with CHESS-style DDL + BIRD CSV descriptions)
```bash
conda activate mats
cd /home/datht/mats-sql-tist
# BIRD dev
python prepare_sft_datasets.py
```

### Step 3: SFT Training (alignment-handbook)
```bash
conda activate mats
cd /home/datht/mats-sql-tist/alignment-handbook
export PYTHONPATH=src/
# BIRD - planner (LLaMA 3.2 3B)
ACCELERATE_LOG_LEVEL=info accelerate launch \
    --config_file recipes/accelerate_configs/multi_gpu.yaml \
    --num_processes 1 \
    scripts/run_sft.py recipes/llama-3b-bird/planner-fft.yaml

# BIRD - validator + fixer (LLaMA 3.2 1B)
ACCELERATE_LOG_LEVEL=info accelerate launch \
    --config_file recipes/accelerate_configs/multi_gpu.yaml \
    --num_processes 1 \
    scripts/run_sft.py recipes/llama-3b-bird/validator-fixer-fft.yaml
```

### Step 4: ORPO Training (after SFT)
```bash
conda activate mats
cd /home/datht/mats-sql-tist/alignment-handbook
export PYTHONPATH=src/
# See alignment-handbook/scripts/train_bird.sh for full commands
bash scripts/train_bird.sh
```

### Step 5: Evaluation (BIRD dev)
```bash
conda activate mats
cd /home/datht/mats-sql-tist

# Serve agents via vLLM (on TITAN RTX, 24GB)
CUDA_VISIBLE_DEVICES=1 vllm serve /home/datht/huggingface/orpo-llama-3b-iter-3-bird-planner-no-filter-seed107 \

    --output_file output/bird_dev_results.jsonl \
    --model-name llama \
    --api_host http://localhost:8003 \
    --n_processes 8
```

## Syncing Code Updates from Dev Machine

After editing code on the dev machine:

```bash
# On DEV machine:
bash /home/datht/mats-sql-tist/scripts/sync_code.sh gf-henry

# On gf-henry (if alignment-handbook changed):
cd /home/datht/mats-sql-tist/alignment-handbook && pip install -e .
```

## Notes

- **vLLM**: TITAN RTX (24GB, GPU 1) is preferred for planner/selection, RTX 2080 Ti (11GB, GPU 0) for smaller validator/fixer models
- **BM25 indexes**: already built, stored in `data/*/db_contents_index/`
- **BIRD CSV descriptions**: automatically loaded during `prepare_sft_datasets.py` via `utils/bird_csv_utils.py`
- **Schema format**: CHESS-style DDL with inline `-- Column Description | Value Description` (see `utils/db_utils.py`)
