The Packages preferences lets you install, update, and uninstall third-party Python packages directly from inside Silhouette. Packages are installed into a managed directory using Silhouette's embedded Python, keeping them isolated from the system Python. Enter a pip-style spec such as numpy or mcp>=1.0,<2.0 and click Install; the table lists installed packages with version and summary information, and a link opens the packages directory in your file manager.

Install Python packages by typing in the package name and spec (if you want a specific version) and press Install.

Packages can be upgraded or uninstalled by clicking on a package and then pressing Update or Uninstall.
