How to visible the classification or segmentation results?

Traceback (most recent call last):
  File "train_cls.py", line 18, in <module>
    from data_utils.kpconv_loader import KPConvLoader
  File "/home/jiahui/Desktop/ComputerGraph/pointnet/PointCloudLib/data_utils/kpconv_loader.py", line 10, in <module>
    import cpp_wrappers.cpp_neighbors.radius_neighbors as cpp_neighbors
ModuleNotFoundError: No module named 'cpp_wrappers.cpp_neighbors.radius_neighbors'

I fixed this by changing the cpp_wrappers.cpp_neighbors.radius_neighbors to cpp_wrappers.cpp_neighbors.neighbors. But I can't make sure I'm right. So, would you please check it out?

It works.
And the acc is [Epoch 299] val acc=0.8938, best=0.9032.
But I have another question, how did I visible the classification results?
