| # Gradio 5.29.1 — last known-good HF Space version per forum reports. | |
| # We tried 4.44.1 (HfFolder), 5.0.1 (Jinja2 cache bug), 6.18.0 (renders blank | |
| # with no error). 5.29.1 has none of those issues and is broadly used on | |
| # Spaces in 2026. | |
| # discuss.huggingface.co/t/gradio-sdk-5-31-0-fully-dysfunctional-api-on-huggingface | |
| # huggingface_hub<0.34 — gradio 5.29 oauth.py still imports HfFolder. | |
| # Pin fastapi to 0.112.2 — multiple forum reports of blank-page issues fixed | |
| # by this exact pin on HF Spaces in 2026. | |
| gradio==5.29.1 | |
| huggingface_hub>=0.23,<0.34 | |
| # OpenAI client — used as the SDK for the Modal-hosted vLLM endpoint | |
| openai>=1.40 | |
| # Pillow — chroma-key fallback paths, scene composition, sprite loading. | |
| # Listed even though most of the keying ran offline at build time: | |
| # the runtime still touches Pillow if a stray *_raw.png is the only | |
| # file present for a sprite. | |
| Pillow>=10.0 | |
| # cairosvg is OPTIONAL — convert mock SVG cards to PNG. The image | |
| # module gracefully falls back to raw SVG if it's not installed. | |
