When preparing NuScenes data set: Error ModuleNotFoundError: No module named 'av2'

[Tony-syr]

av2 is required for Argoverse2 Dataset, however when I try to build nuscenes dataset, it still require the library. I found the because the initialization process requires building the file OpenPCDet/pcdet/datasets/__init__.py

, which import all required datasets. meanwhile, the requirements file doesn't include av2.

have u solved it?
i have the same question when i process the kitti dataset

[Tony-syr]

@reynerlius Yes, In fact I have not solved it completely, I just commented the line where they import the Argo2Dataset dataset.
So if you don't need to use argo dataset, you can do the same following the same steps:

1. navigate to OpenPCDet/pcdet/datasets/init.py.
2. delete or comment the following lines: Line 15 from .argo2.argo2_dataset import Argo2Dataset and Line 27 'Argo2Dataset': Argo2Dataset
