✅ COMPLETE DIRECTORY SOLUTION FOR HUGGINGFACE DEPLOYMENT

Problem Solved

Fixed the issue where BytePlus couldn't access Generated/, static/, and view_session/ folders because they don't exist in the original HuggingFace repository.

Solution Overview

The app.py now creates the required directories directly in the cache and modifies the BytePlus application to ensure proper directory handling.

How It Works

1. Directory Creation in Cache

.cache/
├── app.py                    ← Modified BytePlus app
├── Generated/               ← Created with 755 permissions
├── static/                  ← Created with 755 permissions
│   ├── css/                ← Subdirectories created
│   ├── js/                 
│   ├── images/
│   └── index.html          ← Static index file
└── view_session/           ← Created with 755 permissions

2. BytePlus App Modification

The launcher automatically modifies the BytePlus app by injecting directory creation code:

def ensure_directories_exist():
    """Ensure required directories exist for BytePlus operation."""
    required_dirs = ["Generated", "static", "view_session"]
    
    for dir_name in required_dirs:
        dir_path = Path(dir_name)
        if not dir_path.exists():
            dir_path.mkdir(parents=True, exist_ok=True)
            print(f"Created directory: {dir_path}")
        
        # Set proper permissions and create subdirectories

3. Automatic Operation

• Runs every time BytePlus starts
• Creates directories if they don't exist
• Sets proper 755 permissions
• Creates necessary subdirectories for static files

Success Verification

✅ Directory Structure Created:

• ✅ .cache/Generated/ - 755 permissions, writable
• ✅ .cache/static/ - With css/, js/, images/ subdirectories
• ✅ .cache/view_session/ - Ready for session management
• ✅ Static index file created

✅ BytePlus App Modified:

• ✅ Directory creation code injected at startup
• ✅ ensure_directories_exist() function added
