Slicer-Python Packages Use and Install

Support
9

I’ve tried this on the latest nightly version and it all works well for me!

  1. Start Slicer as administrator: in the start menu, instead of left-click on the Slicer icon, use right-click, then select More... and Run as Administrator.

  2. Install a package by using pip. For example, installing of requests package:

Enter this into the Python interactor:

import pip
pip.main(['install', 'requests'])

The package is successfully downloaded and installed:

Dependent packages are updated, therefore before using the installed requests package, you need to restart Slicer (you can use the restart() command in the Python console).
