If you know about Lizzie already, she has Leela already built into her as well as analysis option.
The link you provided is for her older sister, who was trained on human games and is inferior to Leela Zero which ships with Lizzie and is modelled after AlphaGo Zero (entirely self taught).
You can find the latest release of Lizzie at Releases · featurecat/lizzie · GitHub
Running a release
Just follow the instructions in the provided readme in the release.
The first run may take a while because Leela Zero needs to set up the OpenCL tunings and download the latest network if it is not present. Just hang tight, and wait for it to finish, then you will see Leela Zero’s analysis displayed on the board.
The readme file will also give instructions on how to load an sgf that is saved on your computer and how to have Lizzie automatically analyse the game (this too may take a while if you don’t have a powerful graphics card).
