Hello,

i just want inform you the " BlenderColab.ipynb" it was working perfectly good untill now,
you get a CUDA ERROR and
Found no Cycles device of the specified type

Any idea how to fix ?

This version don't require a authentication with google drive storage. It saves in the colab running section. The user just need to upload the .blend file into section.

This code was modified to render only one frame. But its almost identical to the video version.

Here is the code

Download Blender from Blender Repository.

#Other Versions are here: https://download.blender.org/release/
#=====================================
!wget https://download.blender.org/release/Blender2.93/blender-2.93.5-linux-x64.tar.xz

Unzip Blender

!tar xf blender-2.93.5-linux-x64.tar.xz

Deletes the Default libtcmalloc-minimal4 version and installs the Ubuntu default version

import os
os.environ["LD_PRELOAD"] = ""
#Deletes wrong Version of libtcmalloc-minimal4
!apt remove libtcmalloc-minimal4
#Installs correct version of libtcmalloc-minimal4
!apt install libtcmalloc-minimal4
#Adds this library to the user environment
os.environ["LD_PRELOAD"] = "/usr/lib/x86_64-linux-gnu/libtcmalloc_minimal.so.4.3.0"

Path of Blender File to be Rendered

filename = 'render.blend'

Render Single Frame:

#Render Single Frame: Change -f 1 to -f 100 to render frame 100 for example
#===========================================================================

With debug on

#!./blender-2.93.5-linux-x64/blender -b $filename -noaudio -E 'CYCLES' --debug-all -o "/content/render" -f 1 -F 'PNG' -- --cycles-device CUDA

With debug off

!./blender-2.93.5-linux-x64/blender -b $filename -noaudio -E 'CYCLES' -o "/content/render" -f 100 -F 'PNG' -- --cycles-device CUDA

Can some one help me???

If you get an error

Device does not support queues

then replace --cycles-device OPTIX with --cycles-device CUDA
