after installing those drivers I couldn't boot into my system and had to revert to the older drivers (I probably should upgrade to Ubuntu 19.04 (update: this works fine with standard drivers; what also worked was installing the 5.1 kernel on 18.04, even without newer drivers))

there seems to be a bug in this thread where the latest post isn't always displayed

Has anyone tried LeelaFish yet? I'd see it as Leela with Stockfish tactical blunder check enabled. Supposedly it's 30 elo higher than Leela alone. See https://github.com/killerducky/lc0/wiki/LeelaFish for more info, don't forget to  link 'AuxEngineFile' to Stockfish, otherwise it's just lc0 running.

Probably not important for most, but after installing the latest Linux drivers for my AMD GPU (from ppa:oibaf/graphics-drivers for those interested), my mouse isn't hanging anymore when I put lc0 on.

Thanks guys, I get the eval better now. Does anyone know how to find the best settings for a GPU (nvidia 1060)?


Defaults are fine.

I do use Cuda, the evaluation puzzles me. I am used to seeing scores far lower than LcO gives for positions. Have you noticed this?


The latest lc0 version has a re-scaled formula to convert winning percentage to centipawns. The scores are now much less extreme, and were calibrated to the average of Stockfish/Komodo scores in TCEC15, or something. So it's more comparable to a classic engine now.

I believe the one playing in TCEC had the old formula. You can change it in the settings.

Yes it is explained at https://github.com/LeelaChessZero/lc0/wiki/Technical-Explanation-of-Leela-Chess-...
+3,36 would mean 90% probabily of a win for white.

For e.g. Houdini only +1,5 already means 90% probability of a win for white see http://www.cruxis.com/chess/houdini.htm

So you should make a conversion from 1 scale to another.

can I ask what AMD card you're using? probably way better than mine


My AMD FX(tm)-6300 6 core processor 3,5Ghz is configured with a Nvidia Geforce GTX 960. That is average nowadays.

but since you have an Nvidia card, you probably use the (fast) Cuda version of Lc0 after all
I think JFugre was talking about using the OpenCL version on an AMD graphics card like Radeon

No I am using the OpenCL version. When I try the Cuda version then the lc0 exe just closes without having done any computation. I thought it probably has to do with that I first have to install https://developer.nvidia.com/cuda-zone but then I get the message that I should also install the video studio to let it work properly. I also did that but it kept warning that the video studio is not ok so then I gave up before making some changes which I can't restore anymore afterwards.

Yes I also don't trust the ordo elo much. It is an indication but I consider the match much more valuable.

Yes I think Tony37 is on point according to what I have read. If I understand it is not only the ELO of a network but the number of games (in other words the number of positions) in the network. I have an Nvidia Geforce 1060 card, and am looking to find the best settings as I read that LcO is sort of difficult to get optimized. Having said that I am impressed at the play of LcO.

OpenCL still gets reasonable performance on AMD cards.


Correct. I ran last week a 100 game match 15 minutes + 10 seconds between the commercial Komodo 11 and Lc0 on my AMD (2,5 years old) and Komodo only won with 56 - 44. That is about 50 elo difference. I expect with a longer timecontrol that Lc0 would maybe even win such match. I was using the opencl and a network = 3214 ordo elo. Today there is already a network = 3253 ordo elo.

I will most likely write an article on my blog about it as I guess it is interesting to see what the performance of Lc0 today is on more or less commodity hardware.

I've tried this and essentially LC0 is utterly useless running on windows unless you have a Nvidia Graphics Card. I honestly don't understand why they even offer blas, opencl, its a joke.


OpenCL still gets reasonable performance on AMD cards. OpenCL on a CPU or an Intel iGPU is too slow. They just lack the horsepower.

It's mainly when comparing with the RTX cards that the gap widens up to ludicrous levels (i.e. an RTX 2060 is 15 times faster than a high end AMD card, whereas with a GTX 1060 it's only ~2.8).
