Our client code imports surya.foundation (added in 0.17). The earlier
cu124 torch pin forced uv to downgrade surya to 0.14.1, which doesn't
have that module and depends on a transformers version that lacks
QuantizedCacheConfig. Net: ocr: fail at /healthz.
Drop the cu124 index pin. surya 0.17.1 needs torch >= 2.7, which the
default pypi torch (2.11) satisfies. The deploy host's CUDA 12.4
driver doesn't match torch 2.11's cu13 wheels, so CUDA init warns and
the GPU isn't available — torch + Surya transparently fall back to CPU.
Slower than GPU but correct for MVP. A host driver upgrade later will
unlock GPU with no code changes.
Unit suite stays green.
