As described in This Guide , semantic completion is to be enabled by entering ´TabNine::sem´ into the Text Editor. I restarted Sublime Text and entered this in the Comand Palette; yet no reaction.
When using Sublime- Text, TabNine reminds the user to activate this to enable the python specific autocompletion.
Where to enter this Line : ´TabNine::sem´ ?
Enter it in the document itself. The TabNine::* commands are "magic strings" that TabNine picks from the document as you type.
