riid 2.1.0

PyRIID is a Python package providing modeling and data synthesis utilities for machine learning-based research and development of radioisotope-related detection, identification, and quantification.

Installation

Requirements:

• Python version: 3.8 to 3.10
• Operating systems: Windows, Mac, or Ubuntu

A virtual environment is recommended.

Tests and examples are run via Actions on many combinations of Python version and operating system. You can verify support for your platform by checking the workflow files.

For Use

To use the latest version on PyPI (note: changes are slower to appear here), run:

pip install riid

For the latest features, run:

pip install git+https://github.com/sandialabs/pyriid.git@main

For Development

If you are developing PyRIID, clone this repository and run:

pip install -e ".[dev]"

Examples

Examples for how to use this package can be found here.

Tests

Unit tests for this package can be found here.

Run all unit tests with the following:

python -m unittest tests/*.py -v

You can also run one of the run_tests.* scripts, whichever is appropriate for your platform.

Docs

API documentation can be found here.

Docs can be built locally with the following:

pip install -r pdoc/requirements.txt
pdoc riid -o docs/ --html --template-dir pdoc
