Perform Instance Segmentation on a single .ply file.

Hi!

I'm a bit confused with the readme and not sure how to proceed. I'm trying to use this model for a school project, how can I adapt this repository to perform semantic instance segmentation on a single .ply file.

Unfortunately we do not provide script for it. Please looks at #9, #57.

I'm still confused after reading through those previous issues. Are you saying its not possible to perform inference using the model weights you've already provided?

I don't want to train or test the model extensively, I only need to perform small inference.

It is possible. You can simply do smth like build_model(config).predict(dict(points=pcd)). Where pcd is an array of n_points, 6 for (x, y, z, r, g, b). Just copy the S3DISOneFormer3D model part from our s3dis config and be sure that input point cloud is normalised in the same way as in our s3dis config.

Where does build_model come from, I don't see it in either this or the mmdetection repos
