This is a fork of https://github.com/qertoip/python-package-size.
The main difference to the original is that this fork uses uv instead of pip for temporarily installing the packages, which boost performance by a lot.
Learn after-install weight of any Python package including its dependencies.
The tool will loop over your project dependencies, install each dependency in its own venv and report the actual size including dependency tree.
This is useful for optimizing dependencies of your large applications, libraries or containers.
This is especially useful in machine learning context, where dependencies easily explode into gigabytes.
- pip:
pip install python-package-size-uv - pipx:
pipx install python-package-size-uv
python-package-size-uv -r pyproject.toml
or
python-package-size-uv -r requirements.txt
Determined package sizes:
mypy: 43.7 MB
awscli: 34.0 MB
black: 6.7 MB
pylint: 6.5 MB
pytest: 2.5 MB
Additionally, the result is written in a csv file with default name package_sizes.csv.
