# deploy.sh — One-command setup for vast.ai GPU instances
#
# TWO ways to use this:
#
# Option A — Download from your private HuggingFace repo + run:
#   export HF_TOKEN=your_token
#   pip install huggingface_hub
#   python -c "from huggingface_hub import snapshot_download; snapshot_download('YOUR_USER/td-toolkit', local_dir='.')"
#   bash deploy.sh demo_autopilot.td
#
# Option B — Already uploaded files manually:
#   bash deploy.sh my_pipeline.td

set -e  # Stop on any error

# Colors for pretty output
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
RED='\033[0;31m'
NC='\033[0m' # No Color
