Nuscenes Conversion Process Killed without Error Message

[CWAndersn]

I am currently attempting to reproduce the nuScenes dataset results according to the instructions on the Getting Started page, but encountered the following result during the conversion:

Done loading in 44.116 seconds.

The lack of any error message makes it unclear what went wrong and how to avoid this error to get the proper conversion. Any idea why this occurs?
