Bugs of create_gt_database #210

Closed meng-zha closed 3 years ago

meng-zha commented 3 years ago

Thanks for the wonderful codebase.

  1. The 'LoadPointsFromFile' pipeline in create_groundtruth_database requires the 'coord_type' arguments.
  2. The 'points' in 'example' is of type 'LiDARPoints' while 'box_np_ops.points_in_rbbox' needs numpy.ndarray.
  3. 'BasePoints. getitem ' wants to edit the tuple object 'item', which needs to be converted to list first.

I want to know whether these are caused by bugs or my installation problem. The try of PR has been sent, or these can be fixed by a few minutes by yourself.

Thanks for your commit #211 ,but when i create nuscenes gt, i met this

@songlilucky I test the kitti dataset before, and I have found that the 'coord_type' should be in the ‘LoadPointsFromFile’ pipeline but not in the 'LoadPointsFromMultiSweeps' pipeline. It is a bug. I will fix it immediately.
