Bug

I installed MegaDetector CLI using the instructions on the page
https://microsoft.github.io/MegaDetector/cli/

I ran megadetector detect --input photo.jpg and it gave the error :

Traceback (most recent call last):
File "/home/eira/Projects/megadetector/bin/megadetector", line 5, in

I fixed this by running pip install soundfile

after running megadetector detect --input photo.jpg again, it gave the error :

import pkg_resources as pkg
ModuleNotFoundError: No module named 'pkg_resources'

When I run pip install pkg_resources, I get the error :

ERROR: Could not find a version that satisfies the requirement pkg_resources (from versions: none)
ERROR: No matching distribution found for pkg_resources

Is there something I can do to get it working?

Environment

• PytorchWildlife 1.3.0
• Xubuntu 24.04 LTS
• Python 3.12.3

Minimal Reproducible Example

Install megadetector CLI using the instructions
https://microsoft.github.io/MegaDetector/cli/

run megadetector detect --input photo.jpg

This produces the results above

• Yes I'd like to help by submitting a PR!

Start with the CLI installation instructions and the import path in MegaDetector/src/megadetector_core/detector.py, then reproduce megadetector detect --input photo.jpg under Python 3.12. Check how the CLI declares and installs its dependencies; done means a clean installation reaches the command without the reported missing-module errors.
