DeOldify install.py fails with pkg_resources FileNotFoundError on missing NumPy metadata (tested in A1111 v1.9.3 and Forge v2.5)

[palentir]

Hi,

I’m getting a reproducible install failure when adding sd-webui-deoldify to both AUTOMATIC1111 v1.9.3 and Stable Diffusion Forge v2.5. The extension crashes during install.py with the following traceback:

FileNotFoundError: [Errno 2] No such file or directory:
/home/user/miniconda3/envs/deoldify/lib/python3.10/site-packages/numpy-1.26.2.dist-info/METADATA

The full log shows multiple pkg_resources AttributeError / FileNotFoundError lines, ending in the missing METADATA for NumPy.

What I tested

Python 3.10 (Conda envs on Ubuntu 24.04)

Torch 2.0.1 + cu118 / Torch 2.3.1 + cu121

NumPy 1.26.4

xformers 0.0.19–0.0.27

Tried under both A1111 and Forge (fresh installs, clean envs)

What happens The extension’s install.py script uses pkg_resources.require() to verify dependencies. If any installed package’s .dist-info folder is missing or incomplete (common with modern pip / conda builds), pkg_resources raises FileNotFoundError, aborting the install.

Suggestion Consider replacing pkg_resources checks with modern importlib.metadata (Python 3.8+) or simply relying on requirements.txt to avoid this crash on newer environments.

Thanks — aside from this issue, DeOldify works great once installed manually.
