""" Pixal3D HF Space Proxy ====================== This is a lightweight proxy app for HF Space that redirects users to a locally deployed Gradio share link. Setup: 1. Deploy this as your HF Space app.py 2. Set HF Space Secret: REMOTE_URL = your local share link (e.g. https://xxxxx.gradio.live) 3. Users visiting the HF Space will be seamlessly redirected to your local instance.

⚡ Remote GPU Instance Not Connected

This Space acts as a proxy to a locally-deployed Pixal3D instance running on a dedicated GPU.

To connect, set the REMOTE_URL secret in this Space's settings to your Gradio share link.
