nuScenes lidarseg evaluation on EvalAI fails without returning any error

[jialeli1]

Hi. I tried to submit the test results of lidarseg and also got an error with no information. I passed the local file validation using nuscenes.eval.lidarseg.validate_submission

I also opened an issue here.

Before getting an official response, I would like to confirm with you who submitted successfully whether to zip the results_folder or its subdirectories?

└── results_folder
    ├── lidarseg
    │   └── {test, train, val} <- Contains the .bin files; a .bin file 
    │                             contains the labels of the points in a 
    │                             point cloud         
    └── {test, train, val}
        └── submission.json  <- contains certain information about 
                                the submission

Many thanks
