Bug in kubasic and stucked when generating robust_nerf dataset

[guanjunwu]

Dear authors,
thanks for your great work! I want to use robust_nerf to generate a nerf format dataset, and I faced following problems:

1. When I try to generate kubasic file, the error report:

docker run --rm --interactive \
           --user $(id -u):$(id -g) \                                                              
           --volume "$(pwd):/kubric" \                                                             
           kubricdockerhub/kubruntu \                                                              
           /usr/bin/python3 kubric/scripts/kubasic.py

2. When running robust_nerf dataset generator, the program stucked in :

How can I solve it?
