wedata-ml-runtime

WeData 3.0 机器学习 Notebook Kernel 运行时初始化库。

定位

本包是 WeData 3.0 Notebook 场景下,运行在 DLC 计算容器中的 Kernel 启动适配层。它不改变用户代码,而是通过 monkey patching 把开源的 mlflow / feast 改造成带有 WeData 平台语义(多租户隔离、CAM 鉴权、审计、网关代理)的版本。

前身:wedata-pre-code(同时支持 2.0 和 3.0)

本包仅承载 WeData 3.0 逻辑。WeData 2.0 仍沿用 wedata-pre-code,位于 ../wedata-pre-execute/(已进入维护模式)。

核心能力

  1. 装包标记:配合 DLC 镜像预装 → 运行时刷新 /opt/spark/pip_list.json 系统包快照,消除重复装包告警
  2. 环境变量注入WEDATA_WORKSPACE_ID / MLFLOW_TRACKING_URI / TENCENTCLOUD_SECRET_ID/KEY/TOKEN / KERNEL_WEDATA_* 等 20+ 条
  3. MLflow 客户端重写
    • create/get/search/rename/delete experiment 改走腾讯云 OpenAPI(TC3-HMAC-SHA256 手签)
    • MlflowClient 上所有写操作套装饰器做 workspace_id 校验
  4. Feast gRPC 代理:给 RemoteRegistryX-Target-Service-IP/PORT 请求头走反向代理
  5. 自动 tag 注入:所有 mlflow 对象自动打上 wedata.workspace / wedata.datascience.type / mlflow.user

使用

%pip install wedata-ml-runtime
from wedata_ml_runtime.client import Wedata3PreCodeClient

client = Wedata3PreCodeClient(
    workspace_id="...",

从 wedata-pre-code 迁移

维度 老包 wedata-pre-code 新包 wedata-ml-runtime
PyPI 名 wedata-pre-code wedata-ml-runtime
Python 模块 wedata_pre_code.wedata3.client wedata_ml_runtime.client
客户端类 Wedata3PreCodeClient Wedata3PreCodeClient(保持兼容)
extras pip install "wedata-pre-code[wedata-3]" 无需 extras,主依赖已覆盖
覆盖平台 2.0 + 3.0 仅 3.0

迁移办法:把 %pip install wedata-pre-code[wedata-3]==X.Y.Z 改为 %pip install wedata-ml-runtime==X.Y.Z,并把 from wedata_pre_code.wedata3.client import Wedata3PreCodeClient 改为 from wedata_ml_runtime.client import Wedata3PreCodeClient
