Colab Demo Broken

[kommanderpi]

When installing colmap in colab there seems to be an issue that results in this:

/content/neuralangelo

ModuleNotFoundError Traceback (most recent call last)
in <cell line: 12>()
10 # Import imaginaire modules.
11 from projects.nerf.utils import camera, visualize
---> 12 from third_party.colmap.scripts.python.read_write_model import read_model
13 # Read the COLMAP data.
14 cameras, images, points_3D = read_model(path=f"{colmap_path}/sparse", ext=".bin")

ModuleNotFoundError: No module named 'third_party.colmap'

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

I'm also experiencing that the Colab demo is broken, with a different set of error messages:

I added "nvidia-cuda-toolkit" package when 'sudo apt-get install' in 2nd cell
