Any idea what this means?

[EmptikBest]

Hi, just started a new bot on a raspberry pi 4 model b 8gb ram and when I started it up, I got this after Book. 1.e4:

Any idea what it means?

[Torom]

Do you have a Raspberry Pi compatible version of the engine? The architecture is ARMv8 not x86-64.

[EmptikBest]

Yes, I compiled it with make -j profile-build ARCH=armv8 COMP=gcc.

[Torom]

What happens when you run the engine in the command line and enter go?

[Torom]

Can u post the output of uname -a?

[EmptikBest]

When I run go, it gives me a lot of lines that start with info depth. When I run uname -a (outside of stockfish I'm guessing, since it doesn't work inside stockfish), I get Linux emptikbest-desktop 6.2.0-1004-raspi #5-Ubuntu SMP PREEMPT Mon Apr 3 11:15:14 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux

[Torom]

Hm, that sounds right. I'm not sure why there are problems with BotLi. BotLi and stockfish works fine for me on RaspFish.

[EmptikBest]

Is it the fact that I am using ssh?

[Torom]

You are using ssh to connect to the Raspberry Pi? That's normal. Or do you use ssh for something else? The engine and BotLi are both on the Pi?

Please post your config with the token removed.

[EmptikBest]

Yes, they are both on the Pi. Here is my config with the token removed:

[Torom]

Do you have the 8 GB RAM version of the Raspberry Pi? If not 6 GB of hash is too much.

[EmptikBest]

Yes, it is the 8GB version

[Torom]

Okay, try the following commands one after another:

cd /home/emptikbest/EmptikBot247/BotLi/engines
./stockfish
setoption name Threads value 4
setoption name Hash value 6144
go

[EmptikBest]

Okay, before trying that I tried running user interface again and now I only get this:

Trying the commands you sent now

[EmptikBest]

Oh, I see, it's probably a error with the engine but I don't know why, anyway here's what I get after running go:

Stockfish dev-20230613-7922e07a by the Stockfish developers (see AUTHORS file)
setoption name Threads value 4
setoption name Hash value 6144
go
Killed

I did not 'kill' it by the way

[Torom]

Probably the hash. Try the same with a smaller hash. Let's say 4096.

[EmptikBest]

Yeah, after setting hash to 4096, am getting info depth outputs now, so should I start BotLi after editing the config to set Hash to 4096? Anyway, why doesn't it work with 6144? My Pi has 8GB of RAM, and as indicated in system monitor only 1.1 GiB is used

[Torom]

Yes do that. I'm not sure. It's probably just a little bit too much. But it doesn't matter, a Raspberry Pi is so slow that 4 GB of hash is way more then needed.

[EmptikBest]

Okay, will try after Fairy-Stockfish finishes compiling

[EmptikBest]

Thank you, it worked!

[EmptikBest]

Same error, this time two times in a row. Any idea how to permanently fix this? Do I need to reduce hash even more to something like 2048?

[Torom]

What means same error? Please post the config you're running and the error you're receiving.

[EmptikBest]

Same config.yml that I posted above except for hash 4096. The error I got now out of nowhere is this:

Should I decrease the hash to 2048 now?

[Torom]

Did you increase concurrency above 1?

But I can't imagine 4096 being too much hash unless it runs with concurrency greater 1.

[EmptikBest]

No, concurrency is one.

[Torom]

You could check the journalctl after the crash happened. If there is something with OOM, then the hash is too big. Maybe there are other reasons for the crashes.

[EmptikBest]

When I run journalctl, I do not understand what the output means and if it includes OOM or not, here is the output:

@Torom seems to be working fine now I didn't make any adjustments. Hopefully runs fine for a few days like @RaspFish does for you!
