Hi, @chqzeng
Sounds like your data are similar to SemanticKITTI. We don't provide a specific script for custom data, but you can refer to our codes used in SemanticKITTI. You also need to construct superpoints similar to the codes under "data_prepare."

Our unsupervised method relies on deep networks, so it requires training. We get the pseudo labels with the help of K-Means, then train the deep networks with their supervision to enhance the discrimination of the network's features. Consequently, the features will be increasingly discriminative and clearly better than a random initialized network. So, running without training doesn't work. And I recommend reading our paper at first, as it will facilitate a better understanding of the methodology.

The output should be a folder containing the checkpoints as well as a log file. This log file records training loss, the k-means error, the accuracy of superpoints and primitives, and segmentation results on the validation set. You can find them in our paper.
