📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The primary objective was to enhance the integration of machine learning models with a Flask API, incorporating MLflow for logging and tracking.

Key Activities

  • Developed a train_and_evaluate_model function to encapsulate training of a RandomForestRegressor and integrated it into a Flask API endpoint.
  • Updated the Flask endpoint to include MLflow logging for model retraining, ensuring parameters and metrics are logged effectively.
  • Implemented functionality to save model predictions and actual values as CSV files in MLflow, along with generating diagnostic plots.
  • Corrected a Flask route to ensure proper integration with MLflow, fixing the return statement alignment.
  • Revised the /predict endpoint to select the latest model and preprocessor, enhancing error handling and managing missing values.
  • Reviewed best practices for Python module imports to improve project structure and maintainability.

Achievements

  • Successfully integrated MLflow logging into the Flask API, improving model tracking and experiment management.
  • Enhanced the /predict endpoint for better model and preprocessor selection, ensuring robust error handling.

Pending Tasks

  • Further testing is required to validate the robustness of the updated endpoints and logging mechanisms.
  • Consider implementing additional error logging and monitoring for the Flask application.
