I have point clouds for 400 objects. I have also some other features of these objects. For example their weights.

How I can now train model to predict the weight based on the shape(point cloud)?

I have seen pointnet but is seems it is only for classification?

My understanding of your problem s the target is weight and the point cloud are the features.

Creating a different representations of the point cloud that are amenable to machine learning is called feature engineering.

Possible feature engineering options:

Input each individual cloud point.
Calculate total volume of cloud points.
Template matching. Define shapes and then categorize each point cloud into one of those shapes. The shapes could be for the entire point cloud or subsets.
