How do you assign a NNUE file in Stockfish 12

[reflectionofpower]

I ask this question because I had an old one in there and then I figure when I put the new one in with the other deleted and saved it would be the new one but its the old one. Then Did something again and now the NNUE file is renamed differently but still has the NNUE extension.

Then when you go into properties for SF on the EvalFile its the old file name??

Which GUI do you use?

I use Deep Fritz 14 GUI

After changing the eval file, make sure to press the save button.

Press view->engine_output to see the eval file used by Stockfish.

I do that and the nnue file I put it is renamed a different filename but still NNUE extension

* Record stockfish log by writing sf.log in the textbox next to "Debug Log File".
* Change the Evalfile using absolute path of your new eval file for example, c:\chess\nnue\nn.bin where nn.bin is your new eval file.
* Press save
* Press new game
* Adjust level
* Play a move
* Quit GUI
* Post the sf.log, let's see what is in there.

Thanks, I will try this out Wed. Going to bed and I work 10 hour days Monday & Tuesday

You lost me here: "Change the Evalfile using absolute path of your new eval file for example, c:\chess\nnue\nn.bin where nn.bin is your new eval file"
Where is this path. I thought putting in the NNUE file in Stockfish dir and naming it in the GUI was suffice and what's this BIN file??

You could put the nnue net (with a .nnue extension, not sure current SF can take .bin nets) anywhere and provide that path in the GUI under uci options (for example, c:\nets\mynet.nnue).

o yeah,hmm, L try it. I know I have edited UCI options b4. let's see

This is what I am getting from the log. Weired thing I am not using nn-82215d0fd0df.nnue? I had to chop some of it out as posting have a character limit.
