Error when run python run.py --ginc configs/nerf/blender.gin --scene chair --ginb run.run_train=False

[AutoSenseTech]

Hi, first thanks for your work. I am new to deep learning and have just started to learn about NERF. When I run the command

python run.py --ginc configs/nerf/blender.gin --scene chair --ginb run.run_train=False

I encounter some errors. Could you please guide me on how to resolve these errors? Also, is it possible that these errors are occurring because I haven't trained the model yet and the checkpoint is a place to save the trained model? thank you in advance.
