Installation

When using poetry or uv, add “cel-python” to the dependencies.

uv add cel-python

The optional RE2 package significantly speeds up regular expression matching.

uv add cel-python[re2]

For other tooling and virtual environment configurations, this can be installed with PIP commands.

python -m pip install cel-python

The optional RE2 package significantly speeds up regular expression matching.

python -m pip install cel-python[re2]

Warning

In the case where the platform is “darwin” and the architecture is “arm64” and python is “3.13”, RE2 may not compile properly during installation.
