Configuring LCZero in Arena

[FWCC1]

Can someone please help with configuring LCZ in Arena. Have followed the steps on LCZ site for Arena but with no luck.How do I put in parameters and I see I still have Zero Hash in use,she is not playing.

You need to create a folder with the following items in it

• lczero.exe*
• libopenblas.dll*
• OpenCL.dll**
• leelaz_opencl_tuning (This file contains tuning parameters calculated for your GPU, and is created automatically on the first run of the training. It can also be created by manually running lczero.exe –tune-only or –full-tuner from the command line, see above. Please note that the initial creation of the file can take several minutes, because the tuning probes your hardware which takes time. Also note that this file is not required if you run the CPU-only version of LCZero.)

I also copy the latest unzipped Network file to the root C drive. I rename it WEIGHT there for simplification. Remember to unzip it....its around 61 MB unzipped. I copy this file to the C Drive because sometimes arena has trouble following the file pathway if its not root. Not sure why.

Now go into the Arena menu Engine management and select new

Point to the lczero file in the folder you created

It will create the engine for you and you can point Arena to the books if any you want to use with the engine.

There will also be an area for Command Lines

add the following text

 -w <filepath_to_network_file> -t <number of threads it should use for engine>

Start a match and it should work.

Thank you ED I have done that I put the folder inside Arena Engines. My problem is in the command lines. Can you put in an example for filepath to network and do I put a number after the -T?

I use -w network-103 -t2 --noponder

Having first renamed the network and placing it in the same directory as the executable.

Thanks David

Here my folder tree(folders marked with italic):

Arena
+Engines
++leelaChess0
+++lczero.exe

+++ibopenblas.dll
+++OpenCL.dll
+++networks

Command line:

Replace hash with your own.

Edward Panek:

Can you or someone else please do a video about how to run it with Arena?

For most of the guys it doesn't work. 

[Edward Panek]

Is it working for you?

[FWCC1]

Hello David I HAVE IT WORKING NOW! I had to put the Network Path in.

I added a few screenshots in Leela wiki page (how to install Leela in arena). Is the instruction easy to follow for new people ? Do I need to add more screenshots ?

https://github.com/glinscott/leela-chess/wiki/Getting-Started

[epunk]

The wiki contains setup guides for various GUI's already, why create a separate one? See https://github.com/glinscott/leela-chess/wiki/Running-LCZero-in-a-Chess-GUI
Please check what's there already before adding content.
If it's about screenshots, add them to the existing guide for Arena.

[Nay Lin Tun]

Oops, my bad. I didn't see that, I will remove my screenshots.

[Joules Kin]

Still, I think newbies will catch on better if there are screenshots.

[FWCC1]

One more problem,after I put cpus in using -t-8 my comp freezes also if I put in -t-2 threads

[Nay Lin Tun]

Same thing, I put

 -w latest -t 4 

and Leela Freeze ,help,

[Юрий Павлович]

Type should be UCI.

I just discovered that at 5min games LcZero is competitive with the other engines in Arena,I am so pleased because she loses at blitz vs them. When I discovered this was not able to run a whole tournament will run one later especially interested how she does versus old Rybka 2.3.2

[FWCC1]

Meant to say she loses at bullet vs the other engines so I had the thought to increase the time control and it worked.
She is getting stronger.

[FWCC1]

Have to take that back,she is not doing well vs those engines as I thought

[Joules Kin]

On my computer, Leela loses most of the time against Giraffe, and Giraffe loses games against every other engine (such as rybka, toga II and anmon). So yeah it makes sense that leela would struggle with those other engines.

[www.echecs.site]

yes, indeed, see engine ranking

By some reason LCZ always computes to the depth 17, no matter what the settings are. Is there a way to overwrite this?

[Walid Doknichot]

ex...-w 137 -v10000000........137 is the name of networt .

Hello people, I was using files from when Lczero came out. Now I am downloading new ones and I notice that they have another extension and I do not take sand. Example before had the file 6690eb and now download weights_597.txt.gz but when decompressing it has a .pb extension Should I change something ?? Thank you

[tun nay]

If you are using lco engine (cuda version), you dont need to unzip file. The engine can read it.

If you are using Leela Zero Engine, you need to unzip  the *.gz file , and change file name and extension into weights.txt .( you need to put "-w weights.txt" in engine parameter as well).

Details can be seen in Leela blog.

[Walter Paterno]

Thank you very much for your explanation.
