Use when exploring a dataset, training a first model, or preparing a notebook for promotion.\nlicense: MIT\nmetadata:\n  author: Médéric HURIER (Fmind)\n  source: github.com/MLOps-Courses/mlops-coding-skills/tree/main/mlops-prototyping\n  created: 2026-01-25\n  updated: 2026-08-10\n---\n\n# MLOps Prototyping\n\n## Goal\n\nTo create standardized, reproducible, and production-ready prototypes in Jupyter notebooks. This skill enforces a structured layout (Imports -> Configs -> Load -> EDA -> Modeling -> Eval) and robust engineering practices (Pipelines, Split-Verification) to prevent technical debt and data leakage.\n\n## Prerequisites\n\n- **Language**: Python 3.14\n- **Environment**: `uv` managed project (`.venv`), with `ipykernel` in a `notebook` dependency group\n- **Context**: Executed within a `.ipynb` file or converting to one.\n\n## Instructions\n\n### 1. Notebook Structure\n\nEnforce the following linear sections in every notebook to ensure readability and maintainability.\n\n1. **Title & Purpose**: H1 Title and a brief description of the experiment goals.\n1. **Imports**: Group standard libraries, third-party, and usage-specific imports.\n1. **Configs**: Define **Global Constants** (paths, random seeds, hyperparameters) here. No magic numbers deeper in the code.\n1. **Datasets**: Load, validate, and split data.\n1. **Analysis (EDA)**: Inspect target distributions and correlations.\n1. **Modeling**: Define and train `sklearn.pipeline.Pipeline` objects.\n1. **Evaluations**: Compute metrics and visualize performance on held-out data.\n\n### 2. Configuration Standards\n\nExpose all \"knobs\" at the top of the notebook for easy experimentation.\n\n- **Randomness**: Define `RANDOM_STATE = 42` and use it in splits and model initialization.\n- **Paths**: Use `pathlib` for robust path handling.\n\n  ```python\n  from pathlib import Path\n\n  ROOT = Path(\"..\")\n  DATA_PATH = ROOT / \"data\" / \"input.parquet\"\n  ```\n\n- **Hyperparameters**: Group model params (e.g., `N_ESTIMATORS`, `MAX_DEPTH`).\n- **Toggles**: Use booleans for expensive operations (e.g., `USE_GPU = True`, `RUN_GRID_SEARCH = False`).\n\n### 3. Data Management\n\nEnsure data integrity and prevent leakage.\n\n- **Loading**: Prefer `pd.read_parquet` for speed/types, or `pd.read_csv`.\n- **Splitting**:\n  - **Always** split into `X_train`, `X_test`, `y_train`, `y_test` **before** any data-dependent transformations (imputation, scaling).\n  - **Random Split**: Use `sklearn.model_selection.train_test_split` with `stratify` for balanced classification.\n  - **Time Series**: Use `sklearn.model_selection.TimeSeriesSplit` if data has a temporal dimension (do NOT shuffle).\n  - Use `random_state=RANDOM_STATE`.\n\n### 4. Pipeline Construction\n\nProhibit raw data transformations on the full dataset.\n\n- **Mandate**: Use `sklearn.pipeline.Pipeline` or `ColumnTransformer`.\n- **Why**: Automation of `fit` on train and `transform` on test prevents data leakage.\n- **Example**:\n\n  ```python\n  from sklearn.compose import ColumnTransformer\n  from sklearn.impute import SimpleImputer\n  from sklearn.pipeline import Pipeline\n  from sklearn.preprocessing import StandardScaler\n\n  CACHE = \"./.cache\"  # Define a cache directory\n\n  numeric_transformer = Pipeline(\n      steps=[\n          (\"imputer\", SimpleImputer(strategy=\"median\")),\n          (\"scaler\", StandardScaler()),\n      ]\n  )\n\n  preprocessor = ColumnTransformer(\n      transformers=[(\"num\", numeric_transformer, numeric_features)]\n  )\n\n  # Use 'memory' to cache transformer outputs, speeding up GridSearch\n  model = Pipeline(\n      steps=[\n          (\"preprocessor\", preprocessor),\n          (\"classifier\", RandomForestClassifier()),\n      ],\n      memory=CACHE,\n  )\n  ```\n\n### 5. Experiment Tracking from the Notebook\n\nPrototypes are experiments; record them from the first run rather than retrofitting tracking later.\n\n1. **Backend**: Point MLflow at a SQL store, not the deprecated file store: `mlflow.set_tracking_uri(\"sqlite:///mlflow.db\")`. SQLite is a real SQLAlchemy backend, it supports the model registry, and it is the same store shape as a production Postgres — so moving up later is a URI change, not a rewrite.\n1. **Autologging**: `mlflow.autolog()` before `fit` captures parameters, metrics, and the model for scikit-learn without extra code.\n1. **Scope**: Keep one MLflow experiment per notebook question, and name runs after the hypothesis being tested.\n\n### 6. Evaluation & Visualization\n\nGo beyond accuracy/MSE.\n\n- **Metrics**: Use `sklearn.metrics` appropriate for the task (F1, ROC-AUC, RMSE, MAE).\n- **Baselines**: Compare against a \"Dummy\" model (mean/mode) to verify learning.\n- **Visualization**:\n  - **Regression**: Residual plots, Actual vs Predicted.\n  - **Classification**: Confusion Matrix, ROC Curve, Precision-Recall.\n  - **Feature Importance**: Visualize `feature_importances_` or SHAP values.\n\n### 7. Transition to Production\n\nFacilitate the move from notebook to python package (`src/`).\n\n- **Function Refactoring**: Once a block of code is stable (e.g., a complex data cleaning step), refactor it into a function _within_ the notebook. This makes moving it to a `.py` file trivial later.\n- **Cell Tagging**: Use tags like `parameters` (for Papermill) or `export` to mark cells that should be part of the final documentation or automated pipeline.\n- **Clean State**: Ensure the notebook runs top-to-bottom (`Restart Kernel and Run All`) without errors before committing.\n- **Formatting**: Ruff 0.16 formats Python inside Markdown too, so `mise run format` normalizes the snippets you paste into notes and docs. Run `mise run all` before committing a notebook alongside package code.\n- **Next step**: [mlops-industrialization](../mlops-industrialization/SKILL.md) covers the package layout the refactored functions move into.\n\n## Self-Correction Checklist\n\n- [ ] **No Magic Numbers**: Are all parameters in the `Configs` section?\n- [ ] **No Data Leakage**: Is `fit` called ONLY on `X_train`?\n- [ ] **Reproducibility**: Is `random_state` set for all stochastic operations?\n- [ ] **Resilience**: Are paths defined relative to the project root?\n- [ ] **Tracking**: Do runs land in a SQL-backed MLflow store rather than the deprecated file store?\n- [ ] **Clarity**: Does the notebook read like a report (Markdown cells explaining the _Why_)?\n","tagline":"Structure reproducible Jupyter notebooks with a fixed section layout, hoisted configuration, and leakage-free scikit-learn pipelines.
