# ------------------------------------------------------------------
# DEPENDENCY RESOLUTION STRATEGY
#
# pip's resolver refuses to install packages with conflicting
# declared metadata, even when they work fine at runtime. The known
# conflicts are:
#
#   crewai 1.9.3  → openai~=1.83, aiosqlite~=0.21, opentelemetry-sdk~=1.34, pydantic~=2.11, tokenizers~=0.20
#   litellm 1.88.1 → openai>=2.20, tokenizers>=0.21
#   arize-phoenix 17.2.0 → aiosqlite>=0.22, opentelemetry-sdk (any), pydantic-ai-slim (any)
#
# At runtime all version pairs are compatible. The workaround is to
# install in layers with --no-deps for the conflicting packages.
#
# Step 1 — Install base deps (pip resolves these cleanly).
# Step 2 — Override openai + litellm (--no-deps bypasses the ~=1.83/>=2.20 clash).
# Step 3 — Override OTel to 1.42.x (phoenix needs semconv attrs missing from 0.55).
# Step 4 — Install phoenix's heavy transitive deps (scikit-learn, pydantic-ai-slim, …).
# Step 5 — Install arize-phoenix itself (--no-deps bypasses aiosqlite/OTel clash).
