Lizzie is a graphical interface allowing the user to analyze games in real time using Leela Zero. You need Java 8 or higher to run this program.

Just follow the instructions in the provided readme in the release.

The first run will take a while because Leela Zero needs to set up the OpenCL tunings. Just hang tight, and wait for it to finish, then you will see Leela Zero's analysis displayed on the board. Feel free to supply your own tunings, as this will speed up the process. Do this by copying any leelaz_opencl_tuning file you have into the directory.

First, you will need to have a special version of Leela Zero that continually outputs pondering information. You can get this from one of the Lizzie releases or build it yourself; just substitute leelaz-src/UCTSearch.cpp for the UCTSearch.cpp file found in the Leela Zero sources. Then copy the resulting leelaz to the root of the Lizzie directory tree.

You will also need a file of network weights. There is one provided in the Lizzie release package, or you can download one from http://zero.sjeng.org/. Unzip the resulting .gz file (7zip is the recommended program). Save the resulting file in the Lizzie directory as "network". (with no file extension. the full name is "network", NOT network.txt).

The simplest way to build Lizzie is to use Maven.

To build the code and package it:

$ mvn package

$ java -jar "target/lizzie-0.4-shaded.jar"

(or whatever the current version of the shaded jar file is in target/).
