I have been using build tester for a while without a problem. On both of my computers when I try to use it I get this error. I tried reinstalling and had the same issue.
I was wondering if anyone had any ideas? Thanks for the help
Build Tester needs to find the total nodes etc, in the text output of the engine. If you accidentally altered the strings and they don't match exactly, you'll get that error message. Try deleting:
Another possibility is that the tested exe, didn't generate any data. This can happen with Stockfish when you ask for X amount of hash and it tries to allocate large pages for that hash and fails. SF doesn't run in this case and you get no output.
One other issue that can cause the new NNUE SF to not generate any data is if it can't find the default network. Try putting the correct network in the same directory.
