Hello, the results look very impressive in the paper and I'm excited to try out the repository myself but am having some issues with getting the scripts in the Read-Me to run without error.
I downloaded the data and went to the nerfactor section step 1 for learn data-driven BRDF priors. At this point I don't have data/brdf_merl_npz/ims512_envmaph16_spp1, is this something that needs to be generated with data_gen/merl/make_dataset_run.sh? If so, when I follow the instructions in the data_gen folder, I get the following error message when running data_gen/merl/make_dataset_run.sh.
