## 🛎️How to Use
### Install AngelSlim
We recommend using `pip` to install the latest stable version of `AngelSlim`:
```shell
pip install angelslim
```
Alternatively, you can clone the repository and install from source in editable mode:
```shell
cd AngelSlim && python setup.py install
```
For more detailed installation instructions, please refer to the [Installation Documentation](https://angelslim.readthedocs.io/zh-cn/latest/getting_started/installation.html).
### Quick Start
#### Quantization
After installing `AngelSlim`, you can quickly start by running the following script to perform static `FP8` quantization on the `Qwen3-1.7B` model:
* One-click Start
```shell
python3 tools/run.py -c configs/qwen3/fp8_static/qwen3-1_7b_fp8_static.yaml
```
This example will load the HuggingFace model and perform activation value calibration using the `dataset` specified in the config file, saving the quantized model weights.
* Code-based Start
To perform dynamic `FP8` quantization on `Qwen3-1.7B`:
```python
from angelslim.engine import Engine
slim_engine = Engine()
# Prepare model
slim_engine.prepare_model(model_name="Qwen", model_path="Qwen/Qwen3-1.7B",)
# Initialize compressor
slim_engine.prepare_compressor("PTQ", default_method="fp8_dynamic")
# Compress model
slim_engine.run()
# Save compressed model
slim_engine.save("./output")
```
For more details, please refer to the [Quick Start Documentation](https://angelslim.readthedocs.io/zh-cn/latest/getting_started/quickstrat.html).
#### Speculative_Decoding
##### Eagle3 PyTorch Performance Testing
After installing `AngelSlim`, you can quickly start Eagle3 PyTorch performance testing with the following script:
```bash
python3 tools/spec_benchmark.py \
--base-model-path /path/to/base/model \
--eagle-model-path /path/to/eagle/model \
--model-id your_model_id \
--mode both
```
For more details, please refer to the [Quick Start Documentation](https://angelslim.readthedocs.io/zh-cn/latest/getting_started/quickstrat.html).
### Deployment and Testing
### 1. Offline Inference
If you need to load a quantized model via `transformers`, please set the `deploy_backend: huggingface` in the `global` configuration before quantizing the model, or manually modify the `ignored_layers` field in the `config.json` file located in the quantized model output directory to `ignore`.
To test offline inference with a quantized model loaded via `transformers`, run the following command:
```shell
python deploy/offline.py $MODEL_PATH
```
Where `MODEL_PATH` is the path to the quantized model output.
#### 2. API Service Deployment
After specifying the quantized model path `MODEL_PATH`, you can deploy an OpenAI-compatible API service using the following LLMs inference frameworks:
**vLLM**
Use the following script to launch a [vLLM](https://github.com/vllm-project/vllm) server, recommended version `vllm>=0.8.5.post1`. For MOE INT8 quantized models, vllm>=0.9.0 is required.
```shell
bash deploy/run_vllm.sh $MODEL_PATH
```
**SGLang**
Use the following script to launch a [SGLang](https://github.com/sgl-project/sglang) server, recommended version `sglang>=0.4.6.post1`.
```shell
bash deploy/run_sglang.sh $MODEL_PATH
```
#### 3. Service Invocation
Invoke requests via [OpenAI's API format](https://platform.openai.com/docs/api-reference/introduction):
```shell
bash deploy/openai.sh $MODEL_PATH
```
#### 4. Performance Evaluation
Evaluate the performance of quantized model using [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness), recommended version`lm-eval>=0.4.8`:
```shell
bash deploy/lm_eval.sh $MODEL_PATH
```
For more detaileds, please refer to the [Deployment Documentation](https://angelslim.readthedocs.io/zh-cn/latest/deployment/deploy.html).
