MLflow
MLflow
Open-source platform from Databricks.
Core components:
- Tracking: Log parameters, metrics, artifacts
- Projects: Reproducible runs (MLproject file)
- Models: Package and deploy models
- Registry: Model versioning and staging
Strengths: Self-hosted, open-source, model registry, framework integrations
Limitations: Basic visualization, less collaborative features
Key concept: Autologging for major frameworks - automatic metric capture with one line.
Databricks推出的开源平台。
核心组件:
- Tracking(追踪):记录参数、指标、制品
- Projects(项目):可复现的运行环境(基于MLproject文件)
- Models(模型):模型打包与部署
- Registry(注册中心):模型版本管理与 staging 阶段管控
优势:支持自部署、开源、内置模型注册中心、多框架集成
局限性:可视化能力基础、协作功能较少
核心概念:主流框架自动记录——仅需一行代码即可自动捕获指标。
Weights & Biases (W&B)
Weights & Biases (W&B)
Cloud-first experiment tracking with excellent visualization.
Core features:
- Experiment tracking: Metrics, hyperparameters, system stats
- Sweeps: Hyperparameter search (grid, random, Bayesian)
- Artifacts: Dataset and model versioning
- Reports: Shareable documentation
Strengths: Beautiful visualizations, team collaboration, hyperparameter sweeps
Limitations: Cloud-dependent, limited self-hosting
Key concept: + - simple API, powerful features.
wandb.init()wandb.log()优先支持云端的实验追踪工具,具备出色的可视化能力。
核心功能:
- 实验追踪:指标、超参数、系统状态
- Sweeps(调优搜索):超参数搜索(网格、随机、贝叶斯算法)
- Artifacts(制品):数据集与模型版本管理
- Reports(报告):可分享的文档
优势:可视化效果出色、支持团队协作、内置超参数调优搜索
局限性:依赖云端、自部署支持有限
核心概念: + ——简洁API,功能强大。
wandb.init()wandb.log()What to Track
需要追踪的内容
| Category | Examples |
|---|---|
| Hyperparameters | Learning rate, batch size, architecture |
| Metrics | Loss, accuracy, F1, per-epoch values |
| Artifacts | Model checkpoints, configs, datasets |
| System | GPU usage, memory, runtime |
| Code | Git commit, diff, requirements |
| 分类 | 示例 |
|---|---|
| 超参数 | 学习率、批量大小、模型架构 |
| 指标 | 损失值、准确率、F1值、每轮训练数值 |
| 制品 | 模型 checkpoint、配置文件、数据集 |
| 系统状态 | GPU使用率、内存占用、运行时长 |
| 代码信息 | Git提交记录、代码差异、依赖清单 |
Model Registry Concepts
模型注册中心核心概念
| Stage | Purpose |
|---|---|
| None | Just logged, not registered |
| Staging | Testing, validation |
| Production | Serving live traffic |
| Archived | Deprecated, kept for reference |
| 阶段 | 用途 |
|---|---|
| None(未注册) | 仅已记录,未纳入注册中心 |
| Staging(预发布) | 测试、验证阶段 |
| Production(生产环境) | 用于线上服务 |
| Archived(已归档) | 已弃用,仅留作参考 |
