Some commands in README might be incorrect.

In Step 5. Pre-processed instance labels, and new data should be generated in data/scannet/pointgroup_data/

Since train and test data of scannet are placed at different positions, the commands should be:

cd data/scannet/
python prepare_data.py --split train --scannet_path REPO_DIR/data/scannet/scans --pointgroupinst_path [YOUR_PATH]
python prepare_data.py --split test  --scannet_path REPO_DIR/data/scannet/scans_test  --pointgroupinst_path [YOUR_PATH]

There are also errors in function export in prepare_data.py: the conditioning on split should be corrected. This is a small issue and is easy to put up with.
