Not able to run sample demo colab notebook

After successful installation of dependencies in the notebook, I have encountered the following error-

Hi @pranavgundewar ,
Thanks for reporting the problem.
It is solved now. It was a problem of version(torch 1.9 is not compatible with the current version of torch points 3d)
I'll close the issue. If you find something else, you can reopen it.
Best,
