How do you download part of ScanNet for 3D instance segmentation?

@Yang7879 Thanks for your amaizng work, but I got trouble in downloading ScanNetv2 dataset. When I used the script "python2 download-scannet.py -o ScanNetDatav2/", it warned me that "WARNING: You are downloading the entire ScanNet v2 release which requires 1.2TB of space." I have limited space, so how do you download part of ScanNet for 3D instance segmentation?

hi @DRosemei , at the begining the script, you need to modify the list you need to download.

FILETYPES = ['.aggregation.json', '.sens', '.txt', '_vh_clean.ply', '_vh_clean_2.0.010000.segs.json', '_vh_clean_2.ply', '_vh_clean.segs.json', '_vh_clean.aggregation.json', '_vh_clean_2.labels.ply', '_2d-instance.zip', '_2d-instance-filt.zip', '_2d-label.zip', '_2d-label-filt.zip']
#####!!!!!! change to the following
FILETYPES = ['.aggregation.json', '_vh_clean_2.0.010000.segs.json', '_vh_clean_2.ply', '_vh_clean.aggregation.json', '_vh_clean_2.labels.ply']

FILETYPES_TEST = ['.sens', '.txt', '_vh_clean.ply', '_vh_clean_2.ply']
#####!!!!!! change to the following
FILETYPES_TEST = ['_vh_clean_2.ply']
