# Runtime dependencies for the Hugging Face Space.
#
# The previous version pulled sentence-transformers, transformers, tokenizers,
# torch and faiss-cpu -- roughly 2 GB -- to compute ingredient similarity.
# Open Food Facts already canonicalises ingredients into tags, so set overlap
# replaces that entirely. See nutriweb/reco/similarity.py.

# Pinned, and kept identical to `sdk_version` in README.md -- Hugging Face
# Spaces installs the version declared there, not this one. When the two
# drifted (1.40 on the Space, 1.61 locally) the app crashed on st.button(width=),
# an argument that only exists in the newer release. tests/test_deploy.py
# fails if they diverge again.
