RubiChess nnue file corrupt?

Post by MOBMAT »

It has been some time since I DL'ed the latest version of RubiChess.
I DL'ed version 20230918 and installed it into Arena.
When starting, it told me the network nn-c257b2ebf1-20230812.nnue was missing, so I DL'ed it from the RubiChess here:

https://github.com/Matthies/NN

Once DL'ed, it is only 121K in size whereas previous versions are megabytes in size. RubiChess also reports that the network is corrupt or the format is incorrect.

Am I missing something here?

No problems here with this version in Arena 3.5.1, see log file after startup:

2023-11-02 20:23:59,844<--1:info string Reading network nn-c257b2ebf1-20230812.nnue successful. Using NNUE (V5-1024).

At my PC (I'm not sure, but guess that was done by downloading and unzipping of RubiChess-20230918.zip
from github already like this) the binary is in a directory called Windows and the nnue- file is in directory above this one (Windows with binary is a subdirectory of the one with the .nnue)
Alternatively you could try to set full path in UCI- option of the engine to nn-c257b2ebf1-20230812.nnue
, which is about 20Mb big btw and (about that I'm rather sure too) came within the named .zip- file, regards

Thanks,

I totally missed the .nnue file in the zip folder.

It is working fine now.
