Version of pkl file from mmdetection3d

[lacie-life]

Thank you very much for your great work. I'm trying to run your code with KITTI dataset, but I have a problem with pkl file. I use mmdetectin3d version 1.3 for generate pkl file and use this with your create_range_image_in_kitti.py. When run your code, I meet this problem:

Error: string indices must be integers

Do you have any suggestions for me?

Thanks!!!
