when I run train_transformed_rays.py,the error occur.And the argument ray_directions_ablation in train_utils.py is None,but the function in train_transformed_rays.py does not have the correspond input.
thanks.

I'm not the author, but I solved the problem.
The link would be helpful to you: #16 (comment)
After doing this, there are no errors related to the ablation study.

Thanks very much. I added the input ray_directions_ablation=ray_directions.The problem is solved temporarily.

非常感谢。我添加了输入ray_directions_ablation=ray_directions。暂时解决了问题。

He was mentioning the file "nerface_code/nerf-pytorch/nerf/train_utils.py". But actually I do not think it is a good idea to "added the input ray_directions_ablation=ray_directions". It is better to follow the author's suggestion in #16 that commenting all the code with "ablation". I tried this and I can training now.

I try your solution, but I still have the problem.
