# Benchmark evaluation container — one image per benchmark, built via BENCHMARK arg.
#
# Supported values for BENCHMARK:
#   libero       — LIBERO suite (spatial / object / goal / 10 / 90)
#   libero_plus  — LIBERO-plus extended benchmark (requires robosuite, bddl, robomimic)
#   robomme      — RoboMME memory-augmented manipulation benchmark
#   robocasa     — RoboCasa kitchen composite-task benchmark
#
# Build:
#   docker build --build-arg BENCHMARK=libero -f docker/Dockerfile.benchmark \
#                -t lerobot-benchmark-libero .
#
# Run (interactive):
#   docker run --gpus all --rm -it lerobot-benchmark-libero
# Run eval:
#   docker run --gpus all --rm lerobot-benchmark-libero lerobot-eval --help
