No such file or directory: './out/lidar_20Hz/results_nusc.json' when running scripts/ann_generator.sh

Hi,

I was following the procedure as described here, however I got the following exception:

# bash scripts/ann_generator.sh 12 --ann_strategy 'interp' 
Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: './out/lidar_20Hz/results_nusc.json'
loading nuscenes dataset...

are there any instructions on how I can generate or download this file?

thanks in advance.

same problem, need some help

[eotich32]

just comment this line: nusc_20Hz_rst = mmcv.load(opts.lidar_inf_rst_path), then it works this line is just not used
