Problems with cyrillic names of the folders
Basically if any folder has it's name in Cyrillic, Nibbler is going bonkers. Can't load the nets and TBs, only engine load itself works fine. Any ideas?
It's possible it's related to LeelaChessZero/lc0#1474
Possible, but the engine itself loads properly while nets and TBs don't. Here are some pics. Engine itself is located in the same "Engines" directory and in a same folder as the net and loads well and clear as I said.
the engine itself loads properly
Nibbler loads the engine but then passes network and TB paths via setoption, which is what's claimed to be broken in the linked issue. Can you try using setoption directly in the console app?
That is, try running lc0.exe directly and doing:
setoption name WeightsFile value PATH
But replace PATH with the full absolute path (the bottom blue text in your screenshot).
I would predict Lc0 will emit the same error message, meaning it's an Lc0 problem.
You might need to also type...
go infinite
...afterwards (on a new line) just to get it to actually load. In other words, the full thing to do is:
setoption name WeightsFile value PATH
go infinite
Yeah, tried it for the net, no Cyrillic - fine, yes Cyrillic - not fine. This one is an Lc0 issue. But what about TBs? They have the same issue.
An update on the problem: in Nibbler 2.1.4 the warning is now ensilenced (the path pick goes without a hitch), but the problem is still present: trying to run Fish in KBN v K endgame (4-men) with 5-men TBs has no TB hits from Stock.
Hmm. Can you enable logging with the menu Dev --> Logging and turn on everything in the submenu. Then try it and post the log here please.

In a nutshell: If you set a SF NetPath with a Cyrillic folder, it crashes. If you set a TB Path with a Cyrillic folder, it's reading fails and SF continues without TBs. If there is no Cyrillic in Path, SF runs perfectly fine.
By netpath you mean using a Stockfish EvalFile?
What happens if (as before) you try testing in Stockfish directly? Double-click on stockfish.exe or whatever it's called, and do the following:
setoption name EvalFile value PATH
go infinite
(Replacing PATH with the exact absolute path to the network file.)
Actually it's not working for me either, even on boring ASCII paths. Not sure why, I'll look into it.
By netpath you mean using a Stockfish EvalFile?
Yes, I do. Btw, I forgot to tell you, that the default setting of the integrated net looks to be fine.
I managed to test it out and... same thing as Leela on the net! Really?
Where did you get the net? I've asked on the Stockfish Discord and many of the nets available at https://tests.stockfishchess.org/nns are incompatible with SF13.
I downloaded there, but I downloaded the actual default net just like it is delivered in abrok.eu builds. Net in a path with Cyrillic folder included is picked, but trying to 'go infinite' the application just closes/crashes. Path with no Cyrillic works perfectly. TBs are a bit different: Cyrillic path shows 0 TBs found (search probably goes fine without TBs, not tested), non-Cyrillic works fine (reads the TBs properly). That is what I got.
Looks identical to Leela's problem... if this happens even when opening SF in console then it's not a Nibbler issue.
But then I wonder how Arena handles this like it's nothing... Tried it within the console of Arena with both Leela and Fish, everything runs fine! Is some kind of "Translator" used or what?
That's curious and I have no idea.
Stockfish has an issue about this now: https://github.com/official-stockfish/Stockfish/issues/3424
