[bug]Can not save predictions for testset

[Monster88Ra]

Hello,

I noticed that "--save_prediction" is failed ,because it can not import OnlineVoxelizationDatasetBase from lib.dataset. And there are not any codes of OnlineVoxelizationDatasetBase in dataset.py

May you check it?

Thanks

Okay, let me get back to it this weekend.

the problem still exists, making it difficult for test benchmark

Just a workaround, if you want to convert the prediction on voxel points back to original points, you can set return_index and return_inverse to True in the sparse_quantization function here. This will give you the inverse mapping from voxel points to original point cloud and you can test the results on both ScanNet and S3DIS.
