but no persistent_load function was specified.

Hello, when reproducing, I first downloaded the depth_priors network model, then downloaded the scenes listed in the readme, and ran python3 run_nerf.py train with the above data --scene_id <scene, e.g. scene0710_00> --data_dir < directory containing the scenes> --depth_prior_network_path --ckpt_dir But the above problem occurred. Is there a problem with the version of some files?

Hello, I have also encountered this problem when I try to reproduce the project. Do you solve this problem? Could you please tell me how to set the "--depth_prior_network_path "? (I have downloaded the depth completion model from the link provided by the author, and then unzip it to get a file folder "Archive")

The downloaded 'depth_priors network model' model does not need to be decompressed. Simply put the compressed package into the corresponding folder and then execute the command to solve this problem.
