scripts/setup_realtime_final_graph_env.sh

#!/usr/bin/env bash
set -euo pipefail

# Set up a conda environment capable of running the full online GWAM final graph:
# RoboCasa/robosuite + torch + SAM2 code + OpenAI CLIP.
#
# Usage:
#   bash scripts/setup_realtime_final_graph_env.sh robocasa
#
# Notes:
# - This script installs SAM2/CLIP code. The SAM2/CLIP checkpoints are bundled
#   under models/ in the HF package and are used by default.
# - RoboCasa assets are not redistributed here; users must comply with RoboCasa
#   upstream setup/asset instructions.
# - The torch command below targets CUDA 13.0 wheels. Change the index/device for
#   CPU or other CUDA versions.

RoboCasa code deps are installed. If this is a fresh machine, also install/download
RoboCasa kitchen assets according to upstream RoboCasa instructions before running
live simulator tasks. This dataset does not redistribute RoboCasa assets.
