Cuda for Blender 2.8.2 throws cuInit: Unknown error for supported gfxcard

frispete · February 18, 2020, 8:01pm

Hi,

Blender needs a NVIDIA compute capability of 3.0 at least.

In one system (openSUSE Tumbleweed) with this gfxcard:

Blender 2.82 throws an error:

Read prefs: /home/user/.config/blender/2.82/config/userpref.blend
psutil available
CUDA cuInit: Unknown error
Saved session recovery to '/tmp/quit.blend'

Blender quit

Any idea, how to debug this any further?

Did you verify the CUDA install?

Thanks, Robert.

After symlinking gcc-7 and g+±7 to ~/bin/{gcc,g++}, make -k compiled most of the examples, produced 177 items in bin/x86_64/linux/release, but…

Hmm. Any idea on this one?

Robert_Crovella · February 19, 2020, 11:27am

Your driver install is broken. without knowing precisely how you installed the driver, possibly the complete history of your machine, as well as any logs associated with the driver install, I’m not sure I’m able to help further. Anyway that is why you are getting the blender error.

Well, since I install everything with the packet manager, I can provide detailed infos of my installations, that are completely reproducible.

The cuda packages are from:
http://developer.download.nvidia.com/compute/cuda/repos/opensuse15/x86_64

The installed packages are unchanged, apart from these (expected, modified from rpm post section):

.......T.  c /etc/modprobe.d/50-nvidia-default.conf
.......T.    /usr/lib64/xorg/modules/drivers/nvidia_drv.so

This is an openSUSE Tumbleweed 20200214 (most current, Linux Kernel 5.5.2).

The installation doesn’t trigger any messages, apart from the license:

Let me know, what other details you’re interested in.

We are not interested in CUDA at this point. We are interested in the driver install.

None of that info shows me how you installed the driver, or where your driver packages came from. The driver packages you do show did not come from the repo you indicate - you can easily check that yourself.

OpenSuse tumbleweed is not an officially supported distro for CUDA. My suggestion would be to follow the linux install guide carefully:

https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html

get your installers from https://www.nvidia.com/getcuda

Finally fixed it. For some reason, an old/stray /etc/modprobe.d/nvidia.conf file failed to initialize /dev/nvidia-uvm correctly.

Sorry for the churn.

Will know, where to look the next time…

Here I am having the same problem, I installed the driver, from the nvidia website, NVIDIA-Linux-x86_64-495.44.run, one thing I noticed when testing Debian is that with the 460.91.03 driver Blender recognizes the GPU(gtx1050ti) , since the 470 and 495 do not.

I’ve tried everything and still haven’t had success, it only works with the 460.91.03 driver
