bevdet4d Data Preparation #8

Closed Aloaml closed 6 months ago

Aloaml commented 7 months ago

When I run command according to https://github.com/qcraftai/distill-bev/blob/main/docs/DATA.md :

python tools/data_converter/prepare_nuscenes_for_bevdet4d.py

Wrong message:

Traceback (most recent call last):
  File "tools/data_converter/prepare_nuscenes_for_bevdet4d.py", line 120, in <module>
    add_adj_info()
  File "tools/data_converter/prepare_nuscenes_for_bevdet4d.py", line 26, in add_adj_info
    for id in range(len(dataset['infos'])):
KeyError: 'infos'

run:

print(list(dataset.keys()))

out:

['metainfo', 'data_list']

There is no key 'infos' in dict 'dataset'. All command run in docker container.

Did you run the following command before that one? python tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes –virtual --extra-tag nuscenes If you have run this one, did you get any error messages?

Thanks for your reply! You're right. I run create_data.py command in mmdetection3d instead of this project docker container result in something wrong. It could be that there are some issues with the version differences.
