Vgridtools installation

After installing vgridtools, a dialog will appear prompting you to install vgrid. Copy the following commands:

import pip  
pip.main(['install', 'vgrid --upgrade'])

Use the same command after upgrading vgridtools

When QGIS starts, navigate to Plugins → Python Console, select Show Editor, paste the copied commands, and click Run Script.

Restart QGIS, and you'll see DGGS Vgrid in the Processing Toolbox.
