Missing metadata #594

Closed Solacex closed 3 years ago

Solacex commented 3 years ago

Hello, I am trying to config the nuScenes-lidasreg. I have downloaded the whole dataset and the all-meta-data (nuimages-v1.0-all-metadata.tgz). But I found some many .json files are missing, e.g. visibility.json. where can I get them?

Hi. You also need to download the original nuScenes dataset. nuScenes-lidarseg just has new annotations for the same dataset.

Hi， I have downloaded the full dataset. But these are still missing.,,

Solacex commented 3 years ago

I have downloaded the full dataset including the meta-data. After download lidarseg part, I could only found category.json and lidarseg.json.

In that case you probably overwrote the folder when you extracted the files? Download the nuScenes meta data again.

FileNotFoundError: [Errno 2] No such file or directory: 'data/nuscenes/v1.0-mini/visibility.json' I also encountered this problem. I downloaded the original data but did not find the file.

The recommended path is /data/sets/nuscenes... You are missing the leading slash and the sets folder. Double check it's correct.
