Hi, I guess you are referring to the Camera undistort Colab notebook. Indeed it's not giving the original results reported in the blog post. I will take a look.
Curiously, when running the very same notebook on my laptop with a fresh installation of the lluvia python package, the results look as expected:
I will continue investigating.
Thanks, will try a local build shortly.
It seems as if the newer versions of the GPU runtime in Colab do not support the Vulkan driver. When I try to enumerate the available Vulkan devices in a T4 GPU runtime, all I get is the CPU device (using the Mesa driver). I will investigate further how to get Vulkan to work again in Colab.

PR #160 solves the problem. The colab notebook works again.
Let me know if it works for you so I can close this issue.
