Missing poses_bounds.npy file?

[C-H-Chien]

Hi! I downloaded the video subsets of the Local Light Field Fusion (LLFF) as suggested, I get the following error message when trying to run the code:

It seems that there is a missing poses_bounds.npy file which I do not know how to generate or where I can find. It would be highly appreciated if you could kindly guide me to identify where the file is. Thank you!
