Week 04 – OAuth Integration & Space Debugging
Dates: 2025-06-23 – 2025-06-30
Internship: AI/ML Intern at SynerSense Pvt. Ltd.
Mentor: Praveen Kulkarni Sir
Focus
This week involved implementing a working OAuth login experience in Hugging Face Spaces using Gradio and resolving technical deployment issues like Python versions and Label Studio permissions.
Goals for the Week
- Explore Hugging Face Spaces and OAuth flow
- Implement login button using Gradio in a Hugging Face Space
- Display user identity after login with Google/HF credentials
Tasks Completed
| Task | Status | Notes |
|---|---|---|
| Read Hugging Face OAuth docs | ✅ Completed | Understood login flow and scopes |
| Set up basic Gradio login button in Space | ✅ Completed | Used LoginButton() with hf_oauth: true |
| Display username and HF ID after login | ✅ Completed | Accessed data via OAuthProfile object |
| Fixed Python version issues in Space config | ✅ Completed | Replaced python_version: 3.1 with 3.10 |
| Investigated Label Studio deployment errors | ✅ Completed | Found permission issues on /data volume |
Key Learnings
- Hugging Face OAuth is easy to set up using
LoginButton()and metadata config - Environment variables (e.g.,
OAUTH_CLIENT_ID) must be managed through Space config - Docker containers need explicit write permissions for persistent volumes
- Matching Python versions in README prevents HF build errors
Problems Faced & Solutions
| Problem | Solution |
|---|---|
OAuth error: OAUTH_CLIENT_ID missing | Enabled hf_oauth: true in README.md |
Wrong Python version (3.1 not supported) | Changed to python_version: 3.10 |
OAuthProfile missing expected fields | Used .name, .username instead of .email |
Label Studio permission denied on /data | Considered using HF Persistent Storage or setting envs |
📎 References
Goals for Next Week
- Add logout functionality and refresh detection to UI
- Begin API integration for user-specific actions post-login
- Set up secure Label Studio storage configuration
Screenshots (Optional)
Include interface login, authenticated profile, and HF build fixes if available.
“Every error this week became a stepping stone to mastering OAuth, container environments, and platform-specific configs.”
