Lizzie - Leela Zero Interface

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.

See the Wiki for learning more.

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. 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.

Building from source

Building Leela Zero

First, you will need to have a version of Leela Zero that continually outputs pondering information. You can get this from one of the Lizzie releases or build it yourself; just compile from the next branch of Leela Zero (see http://github.com/gcp/leela-zero/tree/next for more details).

$ git clone --recursive --branch next http://github.com/gcp/leela-zero.git

Building Lizzie

The simplest way to build Lizzie is to use Maven.

To build the code and package it:

$ mvn package

Running Lizzie

$ java -jar "target/lizzie-0.7-shaded.jar"

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

After you run this command you should see a GUI start. Lizzie will also start a Leela Zero process that it will communicate with. You can configure the location of Leela Zero from the config.txt file from the folder you started the java command. If Lizzie is unable to start Leela Zero it will display an error and you can fiddle with the config.txt file until you get all the paths correct.

Lizzie will provide multitude of options to load and save SGF files, run an auto analysis and configure the board. To see all the options just hold down the key x (yes, just press and hold the letter x) and you will see all the commands listed in the GUI.
