how to generate this ''render_path_file.npy'

[sumanttyagi]

this requires as input in smerf to zipnerf models how do i feed this ? - https://github.com/google-research/google-research/blob/master/smerf/configs/zipnerf/london.gin

# london
smerf.internal.configs.Config.data_dir = "datasets/london"
smerf.internal.configs.Config.distill_teacher_ckpt_dir = "teachers/london"

# Downsample pixels
smerf.internal.configs.Config.factor = 2

# Render path config
**camp_zipnerf.internal.configs.Config.render_path_file = 'render_path_file.npy'**
camp_zipnerf.internal.configs.Config.render_resolution = (1392, 793)  # (width, height)
camp_zipnerf.internal.configs.Config.render_focal = 606.465479  # in pixels
camp_zipnerf.internal.configs.Config.render_camtype = 'perspective'
