Lczero setup help

I am struggling to get LCZero running on my machine. If anyone can provide help I'd be most grateful. A screenshot of their setup would be ideal. I can use Arena, Scid vs PC , Hiarcs Chess Explorer, Shredder GUI, or Fritz 13. I have followed the instructions for all the GUI's without luck.

Are you going to use a GPU or CPU?

Good chance, I will use both of them.

Since v0.7 no adapter is needed (inBetween, polyglot) for running leela in FritzGUI or ShredderGUI
Just do this:

1) Create a Leela-folder somewhere on your PC in a folder, which is not write protected
(normally C:\ProgramFiles\ChessBase\Engines is writeprotected!) - I created it in my documents-folder.
2) download the Windows GPU Leela files here: https://github.com/glinscott/leela-chess/releases
3) Unzip all files in your leela-folder
4) Download the Network-file here (but NOT the first on top of the list (the newest)):
http://162.217.248.187/networks
5) unpack the network-file, you get a folder. In it a file. Rename it to weights.txt
6) Copy the weights.txt file in your leela-folder
7) start the lczero.exe -file one time with mouse-double-click. That creates a file called "leelaz_opencl_tuning", which is needed! (If you want to run Leela faster, create a small .bat file with one line in it "lczero.exe -w weights.txt --full-tuner" and start that .bat file with double-click. Then you have to wait around 20-30 minutes, while Leela tries around 5000 GPU-configurations in order to find the fastest.)
8) Start FritzGUI or ShredderGUI and create UCI-engine with lczero.exe. It is recommended, to set the number of Threads to the number of CPUs of your system, that makes Leela a little bit faster, although she uses the GPU for main calculations. (Thread is 2 by default)

You don't mention it, but it's probably the best choice for lczero.
Cutechess GUI.

Download here:
https://github.com/cutechess/cutechess/releases

Install lczero by changing network1 to the name of the network to use.

Thanks for all the reply folks. I tried all the methods here, and still no luck. It did install in Cutechess, however, it still does not run. :evil:

maybe you can try in command line in LCzero's directory:

Code: Select all

lczero --tune-only
this should show your present OpenCL devices,
if no devices are shown,
then you will need some OpenCL drivers maybe.

Has anyone notice Lczero does not allow castling? At least in Cutechess?
