Dockerfile

# Nori multi-policy inference image (INFERENCE_ENDPOINT_PLAN step 5).
#
# ONE Dockerfile, per-kind requirements via build arg:
#   docker build --build-arg MODEL_KIND=molmoact2 -t nori-serve-molmoact2 .
#   docker build --build-arg MODEL_KIND=pi05      -t nori-serve-pi05 .
# Run with env MODEL_KIND matching the build arg (the arg only picks which
# requirements file is installed; the env picks the adapter at boot).
#
# Base per kind (BUILD_BASE arg):
#   molmoact2 -> pytorch/pytorch:2.5.1-cuda12.1 (the proven Space stack; never
#     reinstall torch/torchvision/torchaudio on top — ABI break, space/Dockerfile)
#   pi05      -> python:3.12-slim (the pinned lerobot REQUIRES py>=3.12, which no
#     pytorch/pytorch image ships; lerobot's own dep spec then installs the torch
#     it wants — CUDA-bundled pip wheels, host driver via the endpoint runtime.
#     This mirrors lelab's local venv, the combo the pi05 load path was proven on.)
