使用 MLX 快速推理 MiniCPM
如果你使用 Mac 设备进行推理可以直接使用MLX进行推理。
由于 MiniCPM 暂时不支持 mlx 格式转换。您可以下载由 MLX 社群转换好的模型 [MiniCPM-2B-sft-bf16-llama-format-mlx](https://huggingface.co/mlx-community/MiniCPM-2B-sft-bf16-llama-format-mlx)。
并安装对应的依赖包
```bash
pip install mlx-lm
```
这是一个简单的推理代码,使用 Mac 设备推理 MiniCPM-2
```python
python -m mlx_lm.generate --model mlx-community/MiniCPM-2B-sft-bf16-llama-format-mlx --prompt "hello, tell me a joke." --trust-remote-code
```
