datamate 1.0.0

A data organization and compilation system.

Datamate

Datamate is a data and configuration management framework in Python for machine-learning research. It uses the filesystem as memory through Directory objects, providing a programming interface to store and retrieve files in hierarchical structures using HDF5.

Main Features

• Filesystem as memory through Directory objects
• Hierarchical data organization
• Automatic path handling and resolution with pathlib
• Array storage in HDF5 format
• Parallel read/write operations
• Configuration-based compilation and access of data
• Configuration management in YAML files
• Configuration comparison and diffing
• Pandas DataFrame integration
• Directory structure visualization (tree view)
• Experiment status tracking

Example

import datamate
import numpy as np

# Set up experiment directory
datamate.set_root_dir("./experiments")

# Set up experiment configuration
config = {
    "model": "01",
    "optimizer": "Adam",
    "learning_rate": 0.001,
    "n_epochs": 100
}

# Set up experiment directory and store configuration
exp = datamate.Directory("vision_study/model_01", config)

# Store arrays as HDF5 files
exp.images = np.random.rand(100, 64, 64)  # stored as images.h5
exp.responses = np.zeros((100, 1000))     # stored as responses.h5

# Access data
mean_response = exp.responses[:].mean()
