Hello, does someone know why when i render a file in google colab i don’t get a .png output?
i saw this video on how to do it
but in the video it says saved at render.png, but in mine i don’t see anything related to “saved” and no output is generated…
i do know it gets rendered but idk why the png is not saved…
this is what i get:
yeah… same problem for me too. Has colab shut down the blender action, or are we just the 2 people who didn’t get it to work?
Hi. Here are valuable video tutorials (and ready-to-use scripts) that should help you:
The last time I was able to successfully access OPTIX rendering was October 30, 2021.
I can get CUDA rendering using Blender 2.9.3 and 3.0 — sometimes it works, and sometimes it doesn’t — but no OPTIX.
Error: Found no Cycles device of the specified type
Device does not support queues.
Search results for the “queues” error haven’t yet offered a solution, or even an explanation. I’ve noticed that Google returns fewer results on this topic than Duck Duck Go, for whatever reason.
I’ve seen some suggestions that the issue has to do with Colab trying to push back against crypto mining.
I’ve also seen mention that upgrading from Free to a Pro plan might help, but I haven’t seen this verified.
As a Mac user on an older laptop, Colab has been a godsend, but if I have to start paying for renders, I’d probably be better off using a dedicated Blender render farm instead.
I found a solution. Run these commands before running Blender. These update the Nvidia drivers as Colab’s are out of date. I found the solution here: https://github.com/googlecolab/colabtools/issues/2827
!sudo apt install libnvidia-gl-510 nvidia-dkms-510 nvidia-kernel-source-510 libnvidia-compute-510 libnvidia-extra-510 nvidia-compute-utils-510 libnvidia-decode-510 libnvidia-encode-510 nvidia-utils-510 xserver-xorg-video-nvidia-510 libnvidia-cfg1-510 libnvidia-fbc1-510
!sudo apt install nvidia-driver-510-server --yes
Hopefully this works for you!
Just created an account to say Thank You! It totally works!!
Awesome! Can’t wait to give it a try!
Sadly, it didn’t work for me.
When I tried to update the drivers, it reported back:

And when I tried (for the hack of it) to render using OPTIX, I got:

So… 
Yep, I am getting the same error now. Investigating…
This worked for me. This will first remove all the old Nvidia drivers, and then replace the drivers. Tested it with a Tesla T4 machine.
!sudo apt-get purge nvidia*
!sudo add-apt-repository ppa:graphics-drivers/ppa -y
!sudo apt-get update
!sudo apt install nvidia-driver-510 nvidia-dkms-510 -y
I still can’t use OPTIX:

but CUDA is now rendering some of my test files, so I’m back in business.
Attached is my updated .ipynb file. Feel free to suggest tweaks or to share yours.
BlenderColab.ipynb (6.0 KB)
Make sure you are using a OPTIX-enabled GPU. I believe some of the GPUs in the Colab pool do not support OPTIX. The NVIDIA Tesla T4 I am connected to works with Optix just fine.
Getting an OPTIX GPU seems to be luck-of-the-draw, and I haven’t gotten one of those in a long, long time.
But the CUDA machines are still much, much faster than my laptop, so I’m just grateful that I can once again use Colabs. 
Thanks again for your help!
Not a problem!
