When Piebald detects Python environments (e.g. conda or a venv) globally or in your project folder, it provides a menu to activate an environment for use in future RunTerminalCommand tool calls. For example, if you have a venv in your project and you’ve activated that venv in Piebald, Python scripts that the model runs will have access to all packages installed in that venv. Piebald currently supports the following Python environment managers:
  • conda
  • pixi
  • micromamba
  • venvs (through uv or pip)
Please let us know if you’d like support for another tool!

​
Usage

Piebald automatically detects and displays a menu of all global and project-specific Python environments. When there are Python environments available, a badge is added to the top chat bar: pixi_env_available.png Clicking the badge will reveal a menu of all available Python environments. python_environments.png Once you’ve selected a Python environment, the badge will update to show it and Piebald will get and cache environment variables from the environment that you selected. The length of time that the environment variables have been cached is displayed at the bottom of the Python environments menu.

​
Getting environment variables

Piebald gets environment variables from your environment by executing a command using the Python environment manager’s CLI. On Windows:
  • conda environments: conda run -p <prefix> cmd /c set
  • pixi environments: pixi run -e <env name> cmd /c set
  • micromamba environments: micromamba run -p <prefix> cmd /c set
On other platforms:
  • conda environments: conda run -p <prefix> env
  • pixi environments: pixi run -e <env name> env
  • micromamba environments: micromamba run -p <prefix> env
The environment variables are parsed from the output and cached for use in future RunTerminalCommand tool calls.
