Thanks
But where is lc0.dll what also need together with lc0.exe (ver.0.26.3) and cuda-fp16 backend. dll-s?

Here is a Boxed version that was uploaded by Chad on Discord. You will need to have Dot Net 5 installed.

Ceres:

Dot Net: https://dotnet.microsoft.com/download/d ... -installer

I get a 404 error on the boxed ceres.

I can build the LC0 project using the supplied cmd file or the visual studio project.
However, the project is some berserk CMAKE thing that does not allow you to change the project from exe to dll.

Does someone have a solution file that can be modified?

Dan,

Here is a link to the version I compiled on my system. One thing I want to point out is the syntax for the Directory paths much have 2 backslashes in the Ceres.json file.

Code: Select all

  "DirLC0Networks": "C:\\Users\\tedsu\\Desktop\\Ceres",

I have not tried Chad's version, but when I test from the command line I just use "go nodes 346000" to make sure it is working before moving over to GUI.

I will give it a try.

I found the boxed one someone else posted, and it did not work for me.

I do not know if the DLL files are needed or if they are in the boxed unit.
But I get no output.
I also have 2 GPUs and I do not know how to configure them.
But I should make it work before I make it better.

For two GPUs I believe you should have this in your Ceres.json file: "GPU:0", "GPU:1", Also note that the path for syzygy should have two backslashes.

Sorry, I have not.
But it seems to me there are some disturbance in the writing down of Ceres
There is text about a plugin/interface dll what makes the connection between lc0 (CUDA backends) and Ceres
and there is text about the source of Ceres contains the modified lc0 files of CUDA backend.
What is the truth?
