I get the following error when I run rosrun super_fast_object_detection rosInference.py

[ERROR] [1622813649.547097]: bad callback: <function on_scan at 0x7fafb9fdef70> Traceback (most recent call last): File "/opt/ros/noetic/lib/python3/dist-packages/rospy/topics.py", line 750, in _invoke_callback cb(msg) File "/home/ahmed/PCL_OD/SFA3D/ros/src/super_fast_object_detection/src/rosInference.py", line 63, in on_scan bev_map = makeBEVMap(front_lidar, cnf.boundary) File "/home/ahmed/PCL_OD/SFA3D/sfa/data_process/kitti_bevutils.py", line 34, in makeBEVMap , unique_indices, unique_counts = np.unique(PointCloud[:, 0:2], axis=0, return_index=True, return_counts=True) File "<__array_function__ internals>", line 5, in unique File "/home/ahmed/anaconda3/lib/python3.8/site-packages/numpy/lib/arraysetops.py", line 275, in unique ar = ar.reshape(orig_shape[0], -1) ValueError: cannot reshape array of size 0 into shape (0,newaxis)

Any tips to resolve the error?
