Extracting data from NeRF++ is occurring RuntimeError.

[ssxxnnxxtt]

I want to extract data from NeRF++ by type the command "python extract_grid_nerf++.py --config configs/tanks_and_temples/tat_training_truck.txt" on the nerfplusplus file to create .ply file. However, the error was occurred by the picture that I attached in this issue. How can I solve this error?

I use the version of CUDA & pytorch following the picture that I attached in this comment.
