I am trying to segment lidar point cloud using PointCNN on jupyter notebook. But I am getting Index Error on running show_batch() and runtime error on running lr_find()
IndexError: index 7 is out of bounds for axis 0 with size 4
RuntimeError: Assertion `cur_target >= 0 && cur_target < n_classes' failed. at ..\aten\src\THNN/generic/ClassNLLCriterion.c:92
Any pointers that can help me in solving/debugging these error?
P.S. I am not a developer or coder so please excuse any silly mistake.
