Latest Eval file Loading Issue. Engine Crash #52

Open ExtremeMoves opened 8 months ago

ExtremeMoves commented 8 months ago

I got a problem with the ShashChess 34.6 as i am not able to load in newer eval files. The newest eval file that will load up without crashing the engine is nn-5af11540bbfe.nnue which was released quite a few months ago. I tested almost all eval files that is newer than the one i listed above and all of them failed to load crashing the engine. The following below was captured as an "informational" item listed in eventviewer. Not sure if the below error log will help you or not but its posted below.

If the architecture is different, you can't.

Well i understand that but the problem here is that Stockfish has moved on to better network architectures and have been making newer networks as far back as last summer in 2023. I thought ShashChess would have stayed in step with Stockfish builds that use the newer network files. All the newer stockfish builds can read any of the last networks going back many months ago and recent ones as well but ShashChess cannot read these newer files apparently. So i am not sure what else i can say about it. Unless code is added that can allow ShashChess to read in newer network versions?

Just to be clear I am talking about the network files made by the stockfish team available at their website https://tests.stockfishchess.org/nns

I think i know what you will say as i now remembered a post you made a while back in regards to stockfish updates. If i understand this correctly you will not update the core of the engine until the next major release of stockfish. Because of this unfortunately i see that right after the major release of Stockfish 16 they did a small update on July 1, 2023 and added the following.

"Update NNUE architecture to SFNNv7 with larger L1 size of 2048"

So basically any network make beyond June 30, 2023 will not load into ShashChess untill they release Stockfish 17 and then ShashChess will get a major update along with any other modifications from the ShashChess team.

Exactly
