Maybe LcO 26.0 will work?


RC1 works for me, but not with my config-file. But no problem, I'll manage. It seems as if RC1 is the same as the final release of v0.26. I'll try it soon, thanks!

EDIT: I can and will try to see if it is the problem by removing it. But I don't think CB15 uses the config-file when creating the UCI.

Most likely the name for the config is compiled into the executable. You didn't say if the engine error was fatal or not.

You can try renaming the config, then the engine will either raise an error that it can't find it, or possibly just use default values that you may or may not like.

Once you can get the engine to run (with or without errors), issue the "uci" command. The engine is supposed to report all the parameters that it can accept, and their defaults. Anything not in the list you should remove from the config, or comment them out.


The engine works fine when I remove the config-file. There are several parameters that just gave an error message, but some seem to make the engine get stuck. I might try to debug by commenting out all lines and adding them back. Or just create a totally new file with the basics (like multiplexing and number or threads etc).

Thanks for your help!

The problem is my config-file. It contains some values that were recognized in v0.24, but not in v0.25 or v0.26.

Maybe your .exe is not really an executable file? Some things to try:
  • Verify the checksum that should have been provided on your download site.
  • Open in an editor and verify the first bytes (magic bytes) are "MZ".
  • Run from the command line and see if it responds to commands, try winboard or uci protocols.


I haven't verified the checksum, but I might have found the problem by running from the command line. I get an error, which says "Unknown command line flag: --slowmover=2.800000". This line is in my lc0.config-file, which I got from a user in the Discord-group for Leela. Can this be the problem?

EDIT: I can and will try to see if it is the problem by removing it. But I don't think CB15 uses the config-file when creating the UCI.

Did you download from github?


Yes, I tried both via the Lc0 site (which links to GitHub) and directly from Github.

CB15 finds the exe-file, but just doesn't allow creating the engine in the open dialog.

Just changing the weights did not work. What change was needed in the backend?

Check the backend, I think there is some change, I had to play with it a bit.

I am using 25 on CB, it doesn't like some weights. Maybe look at that.


I will have a look, thanks! But I can't even create the UCI for v0.25.x whereas it works fine for v.0.24.x
