No, the executable are all 32-bit so they'll work on both 32-bit and 64-bit.

Update your video drivers. OpenCL support is provided by your video card.

Yes, I know, but I have a integrated graphic chip on the motherboard and the opencl device is actually the CPU itself. So I think I have to use the normal version. By the way, has anyone used the opencl version? I may want to buy a separate video card, but I don't think a low end one helps. Thanks.

Forgive my stupidity, but how does one run this on Linux?

pleiade67 · **#25**

This is a Windows program. So you may run it under wine. This worked under Mac OSX for me (non gpu version), so should be ok with Linux.
It works both as a standalone app or using Gogui with the gtp option.

You can download the engine seperately, a linux compile is included. The Leela interface works well with wine.

You can run the engine with another user interface like GoGui. Under GoGui you can add the engine with it's command and the --gtp command line option:

/home/.../leela_062_linux_x64 --gtp

With the option --threads you can limit the used threads:

/home/.../leela_062_linux_x64 --gtp --threads 1

Good luck

I've juuuuuuuuuuuuust started using Linux yesterday, so thank you for your patience. With your help I've got it running as a Program in GoGui. But I don't know how to run it from the CLI so that I can see the --help options?

EDIT - and I've now figured out that the correct CLI input is (assuming you're in the Leela dir) "./leela_062_linux_x64" ... I'm still unfamiliar with most of the syntax and was omitting the ./ :oops:

If it's any consolation, I've been working with Linux (as an embedded system or server) for about 15 years, next to Windows for desktop use.

I can't even count the times I forget "./" or type "cd /cygdrive/c/..." (because of Cygwin under Windows) in Linux, or try to do Linux stuff in Windows which doesn't work even though Cygwin is installed...

Maybe I missed something - how do I tell Leela that the upper-left group is actually dead?

No idea, I don't even know whether she’d listen ;-)

but maybe contact the developer, Gian-Carlo Pascutto?

Just press "Cancel" instead of "OK" and play a move inside the eyespace. Most of the time the bot resigns instantly when you play the nakade.

Hey guys, version 0.7 was appearently released a couple of days ago.

Changelog:

Quote:

Leela 0.7.0 (2016-09-30)

- Larger DCNN and hence better move pruning.
- Fuseki library built from professional games included. Speeds up opening play.
- (GPU version) Faster dispatching to GPU, speeding up tree search.
- Better selection of critical variations during the tree search.
- Altogether about half a stone stronger than 0.6.2.
- Support for board sizes larger than 25 x 25 has been removed. This made many of the following enhancements much easier.
- Arrow keys can be used to move through a game in analysis mode.
- Engine stays in analysis mode when moving through a game.
- Show Territory reworked to use the calculation from the engine instead of a simplified one from the GUI. Display is now prettier and can show the likelihood graphically.
- Option to show the probabilities from the DCNN as a heatmap.
- Analysis Window providing in-depth display of the move evaluations. Lines can be clicked to show the Principle Variation graphically.
- Windows DPI Scaling can be enabled or disabled via the settings menu.
- Dialogs should now fit better when using nonstandard screen or font sizes.
- Engine runs at lower priority so Windows stays more responsive.
- Windows XP SP2 is now supported as the minimal Windows version.
- OpenCL support is now available for the Linux GTP engines.

Yup, see my comment from a few days ago, in this same thread ;-)

I was curious about Leela's new strength gain. It said only half a stone on the website, but what if you gave it more thinking time?
See the lightly commented game below between Crazystone and Leela 7.0, which I orchestrated out of curiosity. Modest hardware of 4 3.1GHz CPUs and a mid-range gaming GPU from Radeon.

Doesn't csdl have analysis mode that let it calculate the next best move(s) as long as you want?

ez4u · **#37**

When I try to run the GPU version I get an error as shown here. At this point the program stops responding and has to be closed by windows. Anyone else experience this?

I am running windows 7 and Leela correctly detects my GPU as an NVIDIA GTX 750 TI as shown below.

Edit: This seems to have been a driver issue. The NVIDIA updater ran afoul of my firewall settings some time ago without my noticing. Once I updated to the latest driver, Leela worked perfectly and kicked my butt.

Leela is bleeping great for analyzing games, even for strong players. Just give it some more time.

I was wondering how you used Leela for reviewing games. I installed it on Linux and I can play against the engine through other interfaces. But I don't know how to set it in review mode. Do you need the Windows version for that?

pleiade67 · **#39**

For the GTP version you may have a look at:
viewtopic.php?f=18&t=13692

The Windows version with a more friendly interface works smoothly under wine.
It may be used to review your game:

I missed your answer; thank you for your help. I'll give it a try when I have some time to spend.
Would there be any interest if I throw together some small C program to analyse games in a more user-friendly manner on Linux (input sgf, output sgf with comments?)
