9 months ago @nican2018 you mentioned that you downloaded the v1.0-mini data, but from the AssertionError you have provided, it seems you are trying to load the v1.0-trainval data instead
Well. I have been struggling myself. I think I need help now. I'm following this tutorial https://mmdetection3d.readthedocs.io/en/latest/advanced_guides/datasets/nuscenes.html.
After installing all packages, I download the v1.0-mini dataset, and unzip, following this tutorial. https://colab.research.google.com/github/nutonomy/nuscenes-devkit/blob/master/python-sdk/tutorials/nuscenes_tutorial.ipynb#scrollTo=pmfAToXe7Enf.
Then I'm getting error while trying to preprocess the data.

Please did I missed something?
