# Bernini renderer, pinned to a commit for reproducibility. Its pyproject pins
# diffusers==0.35.2 / transformers==4.57.3 / accelerate==0.34.2 and only
# torch>=2.4.0, so installing it does NOT clobber the torch that the ZeroGPU
# base image provides (>=2.8, required for the AOTI path).

# Needed at import / runtime but NOT declared by bernini's pyproject:
sentencepiece          # UMT5 text-encoder tokenizer (tokenizer/spiece.model)

# torchao is INTENTIONALLY NOT installed (was: FP8 dynamic quant). Two blockers
# on the current ZeroGPU base image (torch 2.11.0+cu130):
#   1. torchao's compiled FP8 kernels are incompatible with torch 2.11 (it logs
#      "Skipping import of cpp extensions ... incompatible torch version", see
#      github.com/pytorch/ao/issues/2919) -- so FP8 wouldn't actually accelerate.
#   2. Merely having torchao installed makes diffusers==0.35.2 (pulled in by
#      bernini) probe torchao at import. Its probe imports module paths that newer
#      torchao removed (floatx.float8_layout / uintx.uint4_layout), and the
#      diffusers fallback handler is itself buggy (undefined `logger`), turning a
#      soft warning into a hard import crash that kills the whole app.
# With torchao absent, diffusers skips the probe (is_torchao_available()==False)
# and the app runs the bf16 path. Set BERNINI_FP8=0 (Space variable) to match.
# Revisit FP8 once torch<=2.x / torchao alignment on the base image is sorted.

# torch comes from the ZeroGPU base image (currently 2.11.0+cu130) — do NOT pin
# it. torchvision is NOT in the base image, but bernini imports it
# (`from torchvision import transforms` in data_utils.py), so we add it. Pin to
# the version that matches torch 2.11.0 and pull the cu130 build from the pytorch
# index so it does not drag a CPU torch: torchvision 0.26.0 requires torch==2.11.0,
# already satisfied by the base, so torch is not reinstalled.
