Error when i do 'python run.py --ginc configs/nerf/blender.gin --scene chair'

Thank you for this repo,
I want to learn nerf model on blender dataset, but i meet this issue.

I follow requirement.txt but because of my cuda version, i change the pytorch(=1.13.1), torch-scatter version.
Can you check and give me some solutions ?
Thank you very much.

One tricky solution is to remove DVGO relevant parts. If you are using DVGO models, then you should find for an appropriate version for PyTorch & torch-scatter.

We don't recommend using PyTorch 1.13.1 since it might lack the compatibility.

Thank you for answer :))
