Issue when installing deepface.

[JackZhhhh]

While trying to install deepface using pip install deepface. I keep getting the error below. I tried to uninstall and reinstall lyz4 thinking that was the issue but it didn't work. Can anyone help me out? Thanks.

Hey @JackZhhhh, thanks for the report.
I gave this a try locally, but couldn’t reproduce it. Could you share some details about your environment, like your pip version, Python version, and the output of pip freeze? That’ll help figure out what’s happening.

If you do pip list you should see a package with a version that is empty or none. That's what causes pip to fail.

You can either:

• Uninstall the package using conda or pip
• Manage your environment with conda only (that's how the base Anaconda environment is designed)
• Create a new conda or virtual environment and install packages into that using the latest version of pip

My pip version is 25.1 and my python version is 3.13.

And when I run pip freeze I get the following output:
