uv2conda

Tiny Python package to create a conda environment file from a Python project using uv.

Assuming you have installed uv:

uvx uv2conda \
    --project-dir "/path/to/my/project/" \
    --name "my_conda_env_name" \
    --python "3.12.7" \
    --conda-env-file "my_conda_env.yaml" \
    --requirements-file "requirements.txt" \
    -- \
        --prerelease=allow

Or, in Python:

from uv2conda import CondaEnvironment

environment = CondaEnvironment.from_project_dir(
    project_dir="/path/to/my/project/",
    name="my_conda_env_name",
    python_version="3.12.7",
    uv_args=["--prerelease=allow"],
)
environment.to_pip_requirements_file("requirements.txt")
environment.to_yaml("environment.yaml")

Example for this library:

$ uv2conda --python 3.12.7
