ml-training-base 0.1.0

A base library for ML training (supervised) with environment setup and logging.

ml-training-base

ml-training-base is a Python library providing base classes and utilities for supervised machine learning projects. It includes:

• A configurable logging setup for both console and file outputs.
• Base classes for data loaders (BaseSupervisedDataLoader).
• An environment setup class for deterministic training (TrainingEnvironment), ensuring reproducible runs.
• A base trainer class (BaseSupervisedTrainer) that outlines a typical training workflow in supervised learning.

By using these abstractions, you can quickly spin up a new ML pipeline with consistent structure and easily extend or override specific components to suit your needs.

Features

• Reusable Base Classes: Standard building blocks for data loading, training, callbacks, and environment management.
• Logging Utilities: Automatically configure logging to both console and file, with customizable logging paths.
• Deterministic Environment Setup: Control Python, NumPy, and TensorFlow seeds for reproducible ML experiments.
• Clear Project Structure: Easily extend or override abstract methods in your own data loaders, trainers, or environment logic.

Installation

You can install this package locally via:

pip install ml-training-base

Quick Start

1. Install the package and its dependencies.
2. Create a YAML configuration file (e.g. config.yaml) with your environment, logging, and data settings.
3. Import the classes in your script or Jupyter notebook:

import logging
from ml_training_base.data.utils.logging_utils import configure_logger
from ml_training_base.training.environment.environment import TrainingEnvironment
from ml_training_base.training.trainer import BaseSupervisedTrainer

4. Set up your environment and trainer:

# For example, a custom trainer that inherits from BaseSupervisedTrainer
class MyCustomTrainer(BaseSupervisedTrainer):
    def _setup_model(self):
        # Initialize your model here, e.g., a TensorFlow/Keras or PyTorch model
        pass

    def _build_model(self):
        # Compile or build your model
        pass

    def _setup_callbacks(self):
        # Setup your training callbacks, checkpointing, etc.
        pass

    def _train(self):
        # Implement your training loop or model.fit(...) call
        pass

    def _save_model(self):
        # Save trained model to disk
        pass

    def _evaluate(self):
        # Evaluate your model on the test set
        pass

# Usage:
trainer = MyCustomTrainer(
    config_path="path/to/config.yaml",
    training_env=TrainingEnvironment(logger=logging.getLogger(__name__))
)
trainer.run()

Key Modules

• data/utils/logging_utils.py:
  • Contains configure_logger(log_path) which sets up console/file logging.
• training/environment/base_environment.py:
  • Abstract base class BaseEnvironment for environment setup tasks.
• training/environment/training_environment.py:
  • Implementation of TrainingEnvironment, enabling deterministic training (sets seeds, configures TensorFlow ops, etc.).
• training/trainer.py:
  • Contains BaseSupervisedTrainer, an abstract class to streamline a typical training workflow (environment setup, model creation, training loop, evaluation).
