这是一个本地托管版本的 GitHub Copilot。它在英伟达的 Triton 推理服务器中使用了 SalesForce CodeGen 模型和 FasterTransformer 后端。
前提条件
- Docker
- docker-compose >= 1.28
- 一台计算能力大于 7.0 的英伟达 GPU，以及足够的 VRAM 来运行你想要的模型
- nvidia-docker
- curl 和 zstd，用于下载和解包模型
Copilot 插件
你可以配置官方 VSCode Copilot 插件来使用你的本地服务器。只要编辑你的 settings.json 来添加。
"github.copilot.advanced": {
"debug.overrideEngine": "codegen",
"debug.testOverrideProxyUrl": "http://localhost:5000",
"debug.overrideProxyUrl": "http://localhost:5000"
}
设置
运行设置脚本以选择要使用的模型。 这将从 Huggingface 下载模型，然后将其转换为与 FasterTransformer 一起使用。
$ ./setup.sh
