### Install Dependencies

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Installs the necessary Python packages for SkillRouter. Assumes a CUDA-capable local machine.

```bash
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
```

--------------------------------

### Prediction Format Example

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/evaluation/README.md

This JSON object demonstrates the expected format for prediction files, mapping task IDs to lists of skill IDs.

```json
{
  "task_id_1": ["skill_id_a", "skill_id_b", "skill_id_c"],
  "task_id_2": ["skill_id_x", "skill_id_y", "skill_id_z"]
}
```

--------------------------------

### Run One-Command Evaluation (Make)

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

An alternative command to run the one-command evaluation using 'make'.

```bash
make eval-open-models
```

--------------------------------

### Repository Layout

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Illustrates the directory structure of the SkillRouter project.

```text

├── README.md
├── assets/
│   └── readme/
├── data/
│   └── eval_core/
├── evaluation/
├── manifests/
├── scripts/
└── src/

```

--------------------------------

### Download Evaluation Data

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/data/README.md

Executes a script to download the full benchmark into the data/eval_core directory. Ensure you have the necessary permissions and disk space.

```bash
bash scripts/download_eval_data.sh
```

--------------------------------

### Run One-Command Evaluation

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Executes the released 0.6B embedding and reranker models over the easy and hard benchmark tiers. Outputs are saved to specific directories.

```bash
bash scripts/evaluate_open_models.sh
```

--------------------------------

### Evaluate Open Models with Local Checkpoints

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Runs the evaluation using local checkpoints for the embedding and reranker models by setting environment variables.

```bash
SKILLROUTER_EMB_MODEL_OR_PATH=/path/to/SkillRouter-Embedding-0.6B \
SKILLROUTER_RERANK_MODEL_OR_PATH=/path/to/SkillRouter-Reranker-0.6B \
bash scripts/evaluate_open_models.sh
```

--------------------------------

### End-To-End Pipeline Evaluation

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/evaluation/README.md

This bash script command initiates an end-to-end evaluation of public models across specified tiers (e.g., 'easy' and 'hard').

```bash
bash scripts/evaluate_open_models.sh --tiers easy hard
```

--------------------------------

### Evaluate Prediction File

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/data/eval_core/README.md

This command evaluates a prediction file against a specified tier of the benchmark. Ensure the predictions file path and tier are correct.

```bash
bash scripts/evaluate_predictions.sh \
  --predictions outputs/custom_eval/retrieval/easy.json \
  --tier easy
```

--------------------------------

### Run Custom Retrieval + Rerank Pipeline

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Executes a custom retrieval and rerank pipeline using specified encoder and reranker models. Reranks top-20 candidates with 'flat-full' prompts by default.

```python
python3 -m src.run_open_model_eval \
  --data_root data/eval_core \
  --encoder_model_or_path /path/to/your/encoder \
  --reranker_model_or_path /path/to/your/reranker \
  --tiers easy hard \
  --output_dir outputs/custom_pipeline_eval
```

--------------------------------

### Citation for SkillRouter Paper

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Provides the BibTeX entry for citing the SkillRouter paper.

```bibtex

--------------------------------

### Export Retrieval Predictions

Source: https://github.com/zhengyanzhao1997/skillrouter/blob/main/README.md

Exports retrieval predictions using a specified encoder model and data root. Keeps top-50 candidates by default.

```python
python3 -m src.export_retrieval \
  --encoder_model_or_path /path/to/your/encoder \
  --data_root data/eval_core \
  --output_dir outputs/custom_eval \
  --tiers easy hard
```
