Leela Chess Zero + Fritz 16 gui setup guide

[Hai]

I tried this and it looks good, lczero v0.7 is there but when I try to load the engine: Engine can't be loaded. Why?

Also do we have this Fritz guide with pictures or a 30 seconds video?

What's your processor ?
Here is folder with all files for installing leela in Fritz 15:
https://www.sendspace.com/file/wooxv8

You can install lczero.exe directly or you can try to install Inbetween.exe in your Fritz 16.
I use 1st way - directly install lczero.exe.
But in fritz 16 sometimes after starting you need press button Infinite analysis and after that you can change engines.

I tried second way, doesn't work.

Directly also doesn't work, when I select "create uci engine" and lczero.exe, then the name isn't filled so I can't click ok.

Following this guide with InBetween 1.3 has worked for me (for GPU and CPU version).

Since v0.7 no adapter is needed (inBetween, polyglot) for running leela in Fritz.
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 Fritz 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)

Done.

Thanks Stefan,

the gpu Version here crashes (the SGEMM tuner) on Intel hd 630 graphics).

Is it worth to use the gpu engine with it?
