Creating custom data from Toronto3d For ground and Roadmarking.

[7Vyshak7]

I tried to create a npy file with only two classes(Ground and Road Markings) from the original Toronto3d ply files for custom training on RandLaNet (I am working on a project to classify ground and roadmarkings alone from a point cloud).
So for training the randlanet model with this new data, what all changes we need to create on config file and in training codes?
Any help is much appreciated
