# Multi-Architecture Offline Installation Guide

## Overview
The enhanced `install_offline.sh` script automatically detects your system architecture and uses the appropriate libraries.

## Architecture Support

### 64-bit ARM (aarch64) - Raspberry Pi 4/5 with 64-bit OS
- **Folder used**: `req_libraries/`
- **Files**: 18 wheel files
- **Key packages**: 
  - bcrypt-4.3.0-cp39-abi3-manylinux_2_34_aarch64.whl
  - pillow-11.3.0-cp311-cp311-manylinux_2_27_aarch64.whl
  - psutil-7.0.0-cp36-abi3-manylinux_2_17_aarch64.whl

### 32-bit ARM (armv7l) - Raspberry Pi with 32-bit OS
- **Folder used**: `req_libraries_32bit/`
- **Files**: 18 wheel files  
- **Key packages**:
  - bcrypt-4.3.0-cp311-cp311-linux_armv7l.whl
  - pillow-11.3.0-cp311-cp311-linux_armv7l.whl
  - psutil-6.0.0-cp311-abi3-linux_armv7l.whl

## Usage

### Simple Installation (Auto-Detect)
```bash
./install_offline.sh
```

The script will:
1. Detect your architecture automatically
2. Choose the correct library folder
3. Install the appropriate packages
4. Create a virtual environment
5. Verify installation

### Manual Architecture Check
```bash
uname -m
```
- `aarch64` = 64-bit (uses req_libraries/)
- `armv7l` = 32-bit (uses req_libraries_32bit/)

## Folder Structure
```

├── req_libraries/           # 64-bit ARM wheels
├── req_libraries_32bit/     # 32-bit ARM wheels  
├── install_offline.sh       # Auto-detecting installer
└── requirements.txt         # Package list

## Benefits
- ✅ Single installer for both architectures
- ✅ Automatic architecture detection
- ✅ No manual intervention needed
- ✅ Proper error messages for missing libraries
- ✅ Complete offline installation support
