# Tool_OCR Setup Guide
Complete setup instructions for macOS environment.
## Prerequisites Check
Before starting, verify you have:
- ✅ macOS (Apple Silicon or Intel)
- ✅ Terminal access (zsh or bash)
- ✅ Internet connection for downloads
## Step-by-Step Setup
### Step 1: Install Conda Environment
Run the automated setup script:
```bash
chmod +x setup_conda.sh
./setup_conda.sh
```
**Expected output:**
- If Conda not installed: Downloads and installs Miniconda for Apple Silicon
- If Conda already installed: Creates `tool_ocr` environment with Python 3.10
**If Conda was just installed:**
```bash
# Reload your shell to activate Conda
source ~/.zshrc # if using zsh (default on macOS)
source ~/.bashrc # if using bash
# Run setup script again to create environment
./setup_conda.sh
```
### Step 2: Activate Environment
```bash
conda activate tool_ocr
```
You should see `(tool_ocr)` prefix in your terminal prompt.
### Step 3: Install Python Dependencies
```bash
pip install -r requirements.txt
```
**This will install:**
- FastAPI and Uvicorn (web framework)
- PaddleOCR and PaddlePaddle (OCR engine)
- Image processing libraries (Pillow, OpenCV, pdf2image)
- PDF generation tools (WeasyPrint, Markdown)
- Database tools (SQLAlchemy, PyMySQL, Alembic)
- Authentication libraries (python-jose, passlib)
- Testing tools (pytest, pytest-asyncio)
**Installation time:** ~5-10 minutes depending on your internet speed
### Step 4: Install System Dependencies
```bash
# Install libmagic (required for python-magic file type detection)
brew install libmagic
# Install WeasyPrint dependencies (required for PDF generation)
brew install pango gdk-pixbuf libffi
# Install Pandoc (optional - for enhanced PDF generation)
brew install pandoc
# Install Chinese fonts for PDF output (optional - macOS has built-in Chinese fonts)
brew install --cask font-noto-sans-cjk
# Note: If above fails, skip it - macOS built-in fonts (PingFang SC, Heiti TC) work fine
```
**If Homebrew not installed:**
```bash
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
### Step 5: Configure Environment Variables
```bash
# Copy template
cp .env.example .env
# Edit with your preferred editor
nano .env
# or
code .env
```
**Important settings to verify in `.env`:**
```bash
# Database (pre-configured, should work as-is)
MYSQL_HOST=mysql.theaken.com
MYSQL_PORT=33306
MYSQL_USER=A060
MYSQL_PASSWORD=WLeSCi0yhtc7
MYSQL_DATABASE=db_A060
# Application ports
BACKEND_PORT=12010
FRONTEND_PORT=12011
# Security (CHANGE THIS!)
SECRET_KEY=your-secret-key-here-please-change-this-to-random-string
```
**Generate a secure SECRET_KEY:**
```bash
python -c "import secrets; print(secrets.token_urlsafe(32))"
```
Copy the output and paste it as your `SECRET_KEY` value.
### Step 6: Set Environment Variable for WeasyPrint
Add to your shell config (`~/.zshrc` or `~/.bash_profile`):
```bash
export DYLD_LIBRARY_PATH="/opt/homebrew/lib:$DYLD_LIBRARY_PATH"
```
Then reload:
```bash
source ~/.zshrc # or source ~/.bash_profile
```
### Step 7: Run Service Layer Tests
Verify all services are working:
```bash
cd backend
python test_services.py
```
Expected output:
```
✓ PASS - database
✓ PASS - preprocessor
✓ PASS - pdf_generator
✓ PASS - file_manager
Total: 4-5/5 tests passed
```
**Note:** OCR engine test may fail on first run as PaddleOCR downloads models (~900MB). This is normal.
### Step 8: Create Directory Structure
The directories should already exist, but verify:
```bash
ls -la
```
You should see:
- `backend/` - FastAPI application
- `frontend/` - React application (will be populated later)
- `uploads/` - File upload storage
- `storage/` - Processed results
- `models/` - PaddleOCR models (empty until first run)
- `logs/` - Application logs
### Step 8: Start Backend Server
```bash
cd backend
python -m app.main
```
**Expected output:**
```
INFO: Started server process
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:12010
```
**Test the server:**
Open browser and visit:
- http://localhost:12010 - API root
- http://localhost:12010/docs - Interactive API documentation
- http://localhost:12010/health - Health check endpoint
### Step 9: Download PaddleOCR Models
On first OCR request, PaddleOCR will automatically download models (~900MB).
**To pre-download models manually:**
```bash
python -c "
from paddleocr import PaddleOCR
ocr = PaddleOCR(use_angle_cls=True, lang='ch', use_gpu=False)
print('Models downloaded successfully')
"
```
This will download:
- Detection model: ch_PP-OCRv4_det
- Recognition model: ch_PP-OCRv4_rec
- Angle classifier: ch_ppocr_mobile_v2.0_cls
Models are stored in: `./models/paddleocr/`
## Troubleshooting
### Issue: "conda: command not found"
**Solution:**
```bash
# Reload shell configuration
source ~/.zshrc # or source ~/.bashrc
# If still not working, manually add Conda to PATH
export PATH="$HOME/miniconda3/bin:$PATH"
```
### Issue: PaddlePaddle installation fails
**Solution:**
```bash
# For Apple Silicon Macs, ensure you're using ARM version
pip uninstall paddlepaddle
pip install paddlepaddle --no-cache-dir
```
### Issue: WeasyPrint fails to install
**Solution:**
```bash
# Install required system libraries
brew install cairo pango gdk-pixbuf libffi
pip install --upgrade weasyprint
```
### Issue: Database connection fails
**Solution:**
```bash
# Test database connection
python -c "
import pymysql
conn = pymysql.connect(
host='mysql.theaken.com',
port=33306,
user='A060',
password='WLeSCi0yhtc7',
database='db_A060'
)
print('Database connection OK')
conn.close()
"
```
If this fails, verify:
- Internet connection is active
- Firewall is not blocking port 33306
- Database credentials in `.env` are correct
### Issue: Port 12010 already in use
**Solution:**
```bash
# Find what's using the port
lsof -i :12010
# Kill the process or change port in .env
# Edit BACKEND_PORT=12011 (or any available port)
```
## Next Steps
After successful setup:
1. ✅ Environment is ready
2. ✅ Backend server can start
3. ✅ Database connection configured
**Ready to develop:**
- Implement database models (`backend/app/models/`)
- Create API endpoints (`backend/app/api/v1/`)
- Build OCR service (`backend/app/services/ocr_service.py`)
- Develop frontend UI (`frontend/src/`)
**Start with Phase 1 tasks:**
Refer to [openspec/changes/add-ocr-batch-processing/tasks.md](openspec/changes/add-ocr-batch-processing/tasks.md) for detailed implementation tasks.
## Development Workflow
```bash
# Activate environment
conda activate tool_ocr
# Start backend in development mode (auto-reload)
cd backend
python -m app.main
bash -c "source ~/.zshrc && conda activate tool_ocr && export DYLD_LIBRARY_PATH=/opt/homebrew/lib:$DYLD_LIBRARY_PATH && python -m app.main"
# In another terminal, start frontend
cd frontend
npm run dev
# Run tests
cd backend
pytest tests/ -v
# Check code style
black app/
pylint app/
```
## Background Services
### Automatic Cleanup Scheduler
The application automatically runs a cleanup scheduler that:
- **Runs every**: 1 hour (configurable via `BackgroundTaskManager.cleanup_interval`)
- **Deletes files older than**: 24 hours (configurable via `BackgroundTaskManager.file_retention_hours`)
- **Cleans up**:
- Physical files and directories
- Database records (results, files, batches)
- Expired batches in COMPLETED, FAILED, or PARTIAL status
The cleanup scheduler starts automatically when the backend application starts and stops gracefully on shutdown.
**Monitor cleanup activity:**
```bash
# Watch cleanup logs in real-time
tail -f /tmp/tool_ocr_startup.log | grep cleanup
# Or check application logs
tail -f backend/logs/app.log | grep cleanup
```
### Retry Logic
OCR processing includes automatic retry logic:
- **Maximum retries**: 3 attempts (configurable)
- **Retry delay**: 5 seconds between attempts (configurable)
- **Tracks**: `retry_count` field in database
- **Error handling**: Detailed error messages with retry attempt information
**Configuration** (in [backend/app/services/background_tasks.py](backend/app/services/background_tasks.py)):
```python
task_manager = BackgroundTaskManager(
max_retries=3, # Number of retry attempts
retry_delay=5, # Delay between retries (seconds)
cleanup_interval=3600, # Cleanup runs every hour
file_retention_hours=24 # Keep files for 24 hours
)
```
### Background Task Status
Check if background services are running:
```bash
# Check health endpoint
curl http://localhost:12010/health
# Check application startup logs for cleanup scheduler
grep "cleanup scheduler" /tmp/tool_ocr_startup.log
# Expected output: "Started cleanup scheduler for expired files"
# Expected output: "Starting cleanup scheduler (interval: 3600s, retention: 24h)"
```
## Deactivate Environment
When done working:
```bash
conda deactivate
```
## Environment Management
```bash
# List Conda environments
conda env list
# Remove environment (if needed)
conda env remove -n tool_ocr
# Export environment
conda env export > environment.yml
# Create from exported environment
conda env create -f environment.yml
```

# files such as alembic.ini.
# The default rendered in new alembic.ini files is "os", which uses os.pathsep
# to provide os-dependent path splitting.
#
# Note that in order to support legacy alembic.ini files, this default does NOT
# take place if path_separator is not present in alembic.ini. If this
# option is omitted entirely, fallback logic is as follows:
#
# 1. Parsing of the version_locations option falls back to using the legacy
# "version_path_separator" key, which if absent then falls back to the legacy
# behavior of splitting on spaces and/or commas.
# 2. Parsing of the prepend_sys_path option falls back to the legacy
# behavior of splitting on spaces, commas, or colons.
#
# Valid values for path_separator are:
#
# path_separator = :
# path_separator = ;
# path_separator = space
# path_separator = newline
#
# Use os.pathsep. Default configuration used for new projects.

# React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
## React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
## Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
```js
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
```
You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
```js
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
```
