Is there any problem when using train_loader of scannetV2? about softgroup HOT 5 CLOSED

It seems the dataloader cannot load the data. Could you please check whether your data is in correct path. The train, val and test should be in SoftGroup/dataset/scannetv2/

from softgroup.

Hi thangvubk !
Thanks for your help. However, they are in the correct path. . .

from softgroup.

The problem is your train data has only 2 scans. The default batch size is 4 and drop_last=True, it will ignore your data. See below.

The solution is (1) set drop_last to False, or (2) reduce batch_size to 2.

Thanks thangvubk!
I think maybe it works. I uploaded more 2 scenes for train dataset, so there is 4 scenes.

However, there is an other error occur like below ...
Do you know about this?

What is the GPU model are you using. It is related to spconv. I found a related issue here open-mmlab/OpenPCDet#442
