# This is here because the Intel pip index is broken and returns 200 status codes for every package name, it just doesn't return any package links.
# This makes uv think that the package exists in the Intel pip index, and by default it stops looking at other pip indexes once it finds a match.
# We need uv to continue falling through to the pypi default index to find optimum[openvino] in the pypi index
# the --upgrade actually allows us to *downgrade* torch to the version provided in the Intel pip index

# spaCy is a dependency of misaki (used by kokoro for English phonemization).
# Pre-download the model here because at runtime the portable Python environment
# has no pip/uv, so spacy's auto-download would fail.
