Min Pin

Min Pin is a command-line tool that automatically adds minimum version pins to unpinned packages in conda-friendly YAML files, such as environment.yml or anaconda-project.yml.

Features

• Parses conda list and pip list to retrieve installed package versions.
• Updates YAML files by adding minimum version pins to unpinned packages.
• Handles both conda and pip dependencies.
• Preserves the original structure and comments of the YAML file.

Installation

pip install minpin

Usage

minpin ./environment.yml

Optionally, specify a conda list output file which you can create with conda list > conda_list.txt:

minpin anaconda-project.yml --conda-list conda_list.txt

  - conda-forge
