To configure Qlik Sense Desktop, carry out the following steps: 

1. Locate Settings.ini (this is usually located at C:Users[your user]DocumentsQlikSense). If it is not there, you can create an empty one using Notepad (or another text editor).
2. Add a line with the following content:

SSEPlugin=Linear,localhost:50054 

Make sure there is a blank line at the end of the file.

The following outlines what each parameter means:

• SSEPlugin: This command instructs Qlik Sense to load a SSE plugin.
• Linear: Shortcut name for your connection. This should be unique to your configuration. Any time you type Linear into your chart expressions, Qlik will know that your plugin will handle the calculation, referring to your script's functions.
• localhost: The hostname or IP of where your Python extension is installed.
• 50054: The TCP/IP port.
