Checklist

  • The issue has not been resolved by following the troubleshooting guide
  • The issue exists on a clean installation of Fooocus
  • The issue exists in the current version of Fooocus
  • The issue has not been reported before recently
  • The issue has been reported before but has not been fixed yet

What happened?

The current installation process is failing due to deep architectural incompatibilities between the current Fooocus codebase and the Python 3.12 environment provided by Google Colab. Attempts to patch gradio_hijack.py or force legacy gradio==3.41.2 versions result in cascading dependency conflicts, specifically involving Jinja2 and core internal modules. The current installation method is no longer viable for this environment.

Could you please provide an update to support the current Python 3.12 stack?

Steps to reproduce the problem

Open the official Fooocus Colab notebook.

Execute the installation cells to set up the environment.

Attempt to run the main cell to launch the application.

What should have happened?

Fooocus should launch successfully and provide the Gradio public URL to access the web interface without any dependency errors.

What browsers do you use to access Fooocus?

Google Chrome

Where are you running Fooocus?

Google Colab

What operating system are you using?

Windows 11

Console logs

I am unable to provide the full terminal logs because the environment in Google Colab crashes and terminates immediately during the dependency installation phase, preventing the generation of a complete log file.
