logger.add(sys.stderr, level="SUCCESS")
dbinfo = load_dbinfo(JSON_FILE)
print('Extract 2d features')
PatchVQ.roipool(LegacyRoIPoolModel(), dbinfo, featname='paq2piq', bs=32, clip_size=1)
PatchVQ.soipool('paq2piq', dbinfo)

print('Extract 3d features')
PatchVQ.roipool(RoIPoolModel(backbone=r3d18_K_200ep), dbinfo, featname='r3d18', bs=1, clip_num=40, clip_size=16)
PatchVQ.soipool('r3d18', dbinfo)
