When trying to launch the conversion script to nuscenes, I get the following error:

Could it be that the conda installs a wrong version of genpy?

It's caused by wrong version of std_msgs. You do not need to install genpy, this will only cause more mess. You can fix it by install the ros-sensor-msgs:

conda install conda-forge::ros-sensor-msgs

You can try the dockerfile I wrote, I just pulled a resquest, you can check it https://github.com/tum-traffic-dataset/tum-traffic-dataset-dev-kit/pull/10.
