arcgis.learn show_batch Index Error and lr_find assertion failed error

[AbhishekPandey]

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.

okay so the problem is with the LiDAR classification codes. Since they are not continuous as you can see in In[7] data.classes.

how to solve it? Its simple just reclassify codes to 0,1,2,3,4.....n
