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:
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.
Blender 2.93 OPTIX — Error: Found no Cycles device of the specified type
Blender 3.0 OPTIX — 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.
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:
Blender 3.2.1 (hash a2d59b2dac9e built 2022-07-05 23:53:28)

F0728 04:11:37.977604 13858 device.cpp:389] Device does not support queues.
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.
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.
