I had lc0 working fine on my PC, but after DL'ing 26.3-rc2 it is tossing errors.
I have a GTX1080 (no fp-16 support).
I dl'ed the lc0-v0.26.3-rc2-windows-gpu-nvidia-cuda.zip file
It installed the cuda 11 dll's along with the other lc0 files.
when i run lc0 from a command prompt, I get the following:
v0.26.3-rc2 built Oct 3 2020

Re: lc0 - which package
Strange, I have both GTX 1060 and RTX 2070S. My system is in use right now, but I have been able to run Cudnn and DX12 on the GTX 1060 if I remember correctly. Not sure if I tried Cuda on the 1060, I did use it on the 2070.MOBMAT wrote: ↑Sat Oct 10, 2020 6:28 pm I had lc0 working fine on my PC, but after DL'ing 26.3-rc2 it is tossing errors.

Re: lc0 - which package
There are issues with 10xx card and cuda 11 if I remember correctly from what I read from Lc0 discord. I think 26.3-rc1 is build with cuda 10 and should run on your card.AdminX wrote: ↑Sat Oct 10, 2020 6:43 pmStrange, I have both GTX 1060 and RTX 2070S.

Re: lc0 - which package
You just need to update your nvidia driver so that it supports 11.1

Re: lc0 - which package
You were correct. I "thought" I had the latest version, but I did not. I updated the drivers and now it is working. Doesn't seem to be any faster, but the utilization on the GPU is a lot lower.George Sobala wrote: ↑Sun Oct 11, 2020 5:13 am You just need to update your nvidia driver so that it supports 11.1
