About the openscene_mini_train.pkl and val.pkl #18

Closed jiangxb98 closed 3 months ago

jiangxb98 commented 3 months ago

When I used 1/8 of the mini data, the training data was 5108, but the github log printed is 621 (621*8=4968), and the val data length also not match (5554 vs 6462).

In addition, the evaluation indicators are also different, and the chamfer_distance_inner indicator is missing.

The difference is reasonable, given the mini_trainval is randomly generated as here. The chamfer_distance_inner key is removed. It is now updated as the chamfer_distance key.

jiangxb98 commented 3 months ago

I don't see any explicit random generation, is the random generation due to this code os.listdir('dataset/openscene-v1.1/meta_datas/mini') ?

tomztyang commented 3 months ago

Yes.

Thanks.
