Error running command: colmap vocab_tree_matcher --database_path during ns-process-data

[aidris823]

Given an input of 20 images in a folder located in /vulcanscratch/aidris12/nerfstudio/data/nerfstudio/unprocessed_monkey/, I am trying to run ns-process-data. I am running the following:

ns-process-data images --data /vulcanscratch/aidris12/nerfstudio/data/nerfstudio/unprocessed_monkey/ --output-dir /vulcanscratch/aidris12/nerfstudio/data/nerfstudio/processed_monkey/
However, I am currently running into this problem:

I don't know why this is occurring. I have tried running COLMAP before in another directory, where I ran

ns-process-data images --data /vulcanscratch/aidris12/nerfstudio/data/nerfstudio/unprocessed_teapot/ --output-dir /vulcanscratch/aidris12/nerfstudio/data/nerfstudio/processed_teapot/

The result was the following. Not good, but at least it ran:

They are both folders of png images that COLMAP processes that are even in the same superfolder (/vulcanscratch/aidris12/nerfstudio/data/nerfstudio), but it is freaking out in one folder versus the other.

Is there perhaps a problem with pathing? You may have noticed that I had a folder named nerfstudio/data/nerfstudio, which seems like poor practice. However, I am confused why the pathing to one folder was fine when the other was not.
