IndexError

In trying to run "python train.py configs/knee.yaml" I am seeing this error:

Hi could you please check if the path to the folder of your data is correct? I added an exception in the dataset to verify.

How do i locate the path that call the datasets because i am getting the same error, and i think it has to do with where the datasets is located.

[Abeltemi]

Or where exactly am i suppose to place the extracted mednerf_drr_dataset directory. as it contains both the chest_xrays and knee_xrays

Apologies for the delay, You specify the path in the config file using the datadir argument.

I also encountered this problem when I was running the code. May I ask you if you finally solved this problem? Thank you very much @georgeasrian
