Hi @chenxyyy , I guess your PyTorch version is too new, so that the `add_` function throws this error. Your modification should be correct (pt1.1 https://pytorch.org/docs/1.1.0/torch.html#torch.add v.s. pt1.5 https://pytorch.org/docs/1.5.0/torch.html#torch.add).

I wrote in README that batch_size=2 (labeled+unlabeled per gpu) is currently hardcoded. This is inconvenient, but I'm sorry that the solution is to change the hardcode or to improve the...

Oh yes, your understanding is correct. In fact this reminded me that I noticed this before but forgot to add a comment to this. Adding the labeled set to the...

Why add this? ``` batch_dict['mask'] = batch_dict['mask'][:, :1] ``` Also I forgot, if you want to have labeled_data_batch_size != unlabeled_data_batch_size, https://github.com/THU17cyz/3DIoUMatch-PVRCNN/blob/1aa469fb7b0bdc22fc030f660f741e59a666160c/pcdet/datasets/kitti/kitti_dataset_ssl.py#L398 this should be modified (also hardcoded that labeled and...

And what happened if you did not make the second modification? I have not met with such situation.

Sorry, do you still need help?
