RuntimeError: CUDA error: invalid configuration argument

[jzhzhang]

Hi， thanks for sharing the code. I just test the code:

python train.py --dataset_name scannet --root_dir scene0000_01 --exp_name exp --val_only --ckpt Scannet0000_01.ckpt

And i get the following error:

  File "/home/user/projects/NeRFusion/models/nerfusion.py", line 172, in sample_uniform_and_occupied_cells
    cells += [(torch.cat([indices1, indices2]), torch.cat([coords1, coords2]))]
RuntimeError: CUDA error: invalid configuration argument

The indices2 and coords2 are Size([0]) and Size([0,3]), respectively. It seems to be a BUG and could you give me some quick advice to fix this?

Thanks for this feedback. Can you provide more information? Are you using the provided data and checkpoint? How many computing devices are you using?
