HuggingFace Demo Incomplete — ZeroGPU worker error: InstantiationException

Description

The Hugging Face Space for CompVis / EDGS fails to start on ZeroGPU, returning an InstantiationException during worker initialization. The demo never loads and remains stuck at the ZeroGPU error screen.

This appears to be a backend/runtime startup failure rather than a user input issue.

Environment

• Space: https://huggingface.co/spaces/CompVis/EDGS
• Runtime: ZeroGPU (free tier)
• Browser: Microsoft Edge
• OS: (your OS — e.g., Windows 11 / macOS Ventura)
• Logged-in HF account: Yes
• Region: (optional)

Steps to Reproduce

1. Open the EDGS Space
2. Wait for ZeroGPU worker to start
3. Observe the worker crash before model initialization

Expected Behavior

The Space should start the worker, load the EDGS model, and display the UI for inference.

Actual Behavior

ZeroGPU fails to initialize the worker and returns:

InstantiationException
ZeroGPU worker failed to start

The Space never loads and remains unusable.

Additional Notes

• Other Spaces using ZeroGPU load normally, so this appears specific to EDGS.
• The error suggests a startup or dependency issue in the Space configuration.
• The Space may require CPU/GPU runtime or updated environment files.

Reproduce the failure by opening the CompVis/EDGS Hugging Face Space and waiting for the ZeroGPU worker, then inspect the Space configuration and environment files for the startup or dependency problem. Done means the worker initializes, the EDGS model loads, and the inference UI becomes usable without the InstantiationException.
