Nibbler doesnt work properly with leela chess 0 under windows 7 x64

[Vukica14]

Hello to everyone,
I am happy to have Nibbler and leela chess 0 but v29 of leela doesnt fit with Nibbler 2.4.0 and its working independently when I am running benchmark for example from cmd propmt.

Is there any workaround to help to fix this issue?

Many thanks in advance.

[rooklift]

Is this different from #203 ?

[Vukica14]

It is as I discovered what version of leela is incompatible with nibbler under win7 x64, so I decided to post again.

[rooklift]

I still don't know what to suggest.

Why you close this? maybe someone else has idea.

[rooklift]

I closed it because it's identical to #203 which is still open. Still I'll reopen this and close that one, if you prefer.

[Vukica14]

Thanks. I prefer to keep this one as it is more detailed.

[Vukica14]

its interesting this initial part of log file when I am loading v26.1
Launching D:_LeelaZero\lc0-v0.26.1-windows-gpu-nvidia-cuda\lc0.exe

(failed) --> quit
--> uci

. | _ | |

is that normal behavior?

[rooklift]

It seems for 0.29 you are using the cudnn version but for 0.26 you were using the cuda version - can you try the cuda version of 0.29?

I believe that was it trying to tell the previous engine (which didn't start) to quit, which it can't, because it didn't start.

[Vukica14]

since version 26.2 cuda is transfered into cudNN. I try "go infinite" on cuda v29 but it didnt work so before v26.2 it must be CUDA and after that cudNN.
and, thanks for the clarification.

[rooklift]

OK, I see. But I don't know what to do.

[Vukica14]

I posted also in leela chess but I am still wating for the answer. It seams leela working well but in combo with nibbler making a problems.

[rooklift]

btw, in the other issue you mentioned Stockfish not working either. Can you please turn off Dev --> Show engine state and then post a screenshot of what it looks like when loading Stockfish?

[Vukica14]

sure here is version 15.1 and it is the same for v15

[rooklift]

Please turn off Dev --> Show engine state first.

[Vukica14]

I did, I think

[rooklift]

OFF

[rooklift]

(Or are you saying it doesn't turn off?)

[Vukica14]

(Or are you saying it doesn't turn off?)

sorry I didnt get you. I enabled "enginee state" is there anything else I have to do? But both versions of the stockfish doeasnt work

[Vukica14]

and stockfish both versions works well in fritz 16

[rooklift]

I enabled "enginee state"

Please turn it off.

[Vukica14]

I enabled "enginee state"

Please turn it off.

here it is

[Vukica14]

ooo after GO it works :D

[rooklift]

So how else were you trying to start the analysis, and was that other way not working?

[Vukica14]

and for leela 29

[Vukica14]

So how else were you trying to start the analysis, and was that other way not working?

for versions lower than 26.2 I see that initialization of the enginee (leela) and for higher versions it cant start

[rooklift]

Right, yeah, Leela is definitely failing to start. Could it be a memory issue?

I doubt it will help, but try:

Dev --> Disable hardware acceleration for GUI (turn it on, ticked, enabled)

[rooklift]

And then restart Nibbler.

[Vukica14]

And then restart Nibbler.

I try but it is the same

[rooklift]

Can you post your system hardware info?

[Vukica14]

Can you post your system hardware info?

sure just where to find it?

[rooklift]

Uh. Well I guess I wanted to know how much RAM your computer has, your graphics card, and how much RAM it has as well.

If you don't know them I guess I don't know exactly how one finds them in Windows 7. I would guess your PC is fairly old?

[Vukica14]

here is GPU
GPU: NVIDIA GeForce GTX 850M
. GPU memory: 2 Gb
. GPU clock frequency: 901.5 MHz
. GPU compute capability: 5.0

and I have

[Vukica14]

its bit old but I think still powerful 16GB of RAM and quad core

[rooklift]

Yeah I think it should be good enough. Uh, can you try the Windows OpenCL version of Leela 0.29, just to see if it works?

[Vukica14]

I try and its the same.

Awaiting UCIOK

whats that?

[rooklift]

When a UCI engine starts up, it sends some info and finally the line uciok. The message from Nibbler indicates we never even got this far.

[rooklift]

Actually, now that I think about it, the OpenCL client has a substantial "tuning" period on first run, do you see any output at all on the right side of the window?

this is the window

No prob and many thanks for the wish to help out here.
