Stockfish NNUE

Thanks.
I should learn to read!
Compiled SF so many times, my fingers type the command automatically.

Mine too, and I knew the answer only because I made the same error. At nodchip's repo, the make help target has been updated to include info about the various nnue targets. But not at the repo you cloned.

BTW I now have the same issue others have reported here.
Stockfish_nnue works fine in a console, but I cannot persuade it to read the nn.bin file in either scid or python chess - even though the paths are definitely correct. (Not tried other gui, or Windows.).
Just get a2a3 etc like others, presumably indicating that no bin file has been loaded.

Did you try absolute paths?

The engine should load the net in response to ucinewgame. Does the GUI send that? Can you log communications?

Tried a few things. None of which worked.
File not found or wrong format error.
But works in the console.
ucinewgame does not seem to cause an attempt to reload the nn.bin file.
Thanks for the help, but time for a rest.

Don't know. When you installed the engine in the GUI, did you set a working directory? I assume all paths used by the engine would be relative to that.

Don't have Scid installed, but this engine works fine in ChessX, for example. But I did need to supply both the path to the binary and a directory in which to run. Here's a bit of the config file:

Code: Select all
