No files in color_corr, list index out of range

[abhi-rf]

Hey, thanks for your very cool work. I am trying to reproduce for one specific style image, and I did all of the steps mentioned in the readme. However, I run into the following issue for running with DNerf :

Traceback (most recent call last): File "ref_style_time.py", line 176, in trainer.train(25000, "style") File "me/s-dyrf/hexplane/render/style_trainer_time.py", line 528, in train related_rays_gt = related_rays_gts[tmpl_id % len(num_dict)] IndexError: list index out of range srun: error: node11: task 0: Exited with exit code 1

On investiogation, it comes in from len(num_dict) being 0

num_dict = glob.glob(os.path.join(self.cfg.style.out_dir, "color_corr", "color_corr_*.pt"))

This is because my color_corr folder is empty, I do not know why is that since I followed all the steps and made sure nothing was overlooked!

Thanks for your help @xingyi-li !

Update: Solved by starting the process again, the empty color_corr folder forced it to Preload without it having anything else inside! Thanks!!

Hi! I get a similar issue while preparing the data again using all the steps in the readme.

I get the issue at the following command bash scripts/preprocess_dnerf_all.sh, specifically the python ref_regist_time.pycommand

Please let me know what I am doing different as somewhere, an empty depth map is being returned! @xingyi-li
