1. Log Analysis
Review system logs and error messages to identify root causes of problems.
Check Locations:
• Application log files
• System event logs
• GPU driver logs
• Network connection logs
2. Performance Monitoring
Monitor system resource usage in real-time to identify performance bottlenecks.
Monitoring Metrics:
• CPU usage rate
• GPU usage and temperature
• Memory consumption
• Disk I/O performance
3. Environment Verification
Verify the correctness of software environment configuration and dependencies.
Check Items:
• Python version compatibility
• Dependency library versions
• Environment variable settings
• File permission configuration
GPU Memory Insufficient (CUDA Out of Memory)
Symptoms: Generation process stops suddenly with memory error
Solutions:
- Reduce batch size
- Decrease image resolution
- Use gradient checkpointing
- Clear GPU cache: torch.cuda.empty_cache()
- Enable CPU offloading
Model Loading Failure
Symptoms: Cannot load model files, reports corruption or missing files
Solutions:
- Verify model file integrity (MD5/SHA256)
- Re-download model files
- Check file paths and permissions
- Clear model cache directory
- Use alternative model sources
Poor Generation Quality
Symptoms: Images are blurry, distorted, or don't meet expectations
Solutions:
- Adjust sampling steps (increase to 50-100 steps)
- Optimize prompt descriptions
- Adjust CFG Scale parameters (7-15)
- Use high-quality samplers (DPM++, Euler a)
- Increase image resolution
API Connection Issues
Symptoms: Connection timeout, authentication failure, or service unavailable
Solutions:
- Check network connection status
- Verify API key validity
- Configure proxy server
- Increase request timeout
- Use alternative API endpoints
System Maintenance
- Regular driver updates
- Clear system cache
- Monitor hardware temperature
- Backup important configurations
Data Management
- Regular model file backups
- Verify file integrity
- Manage storage space
- Establish version control
1. Immediate Response (0-5 minutes)
- • Stop current operations, save work progress
- • Record error information and operation steps
- • Check system resource usage
2. Problem Diagnosis (5-15 minutes)
- • Analyze log files and error messages
- • Determine problem type and severity
- • Search for relevant solutions
3. Solution Implementation (15-30 minutes)
- • Implement solutions by priority
- • Test repair effectiveness
- • Record resolution process and results
4. Follow-up (After 30 minutes)
- • Verify system stability
- • Update troubleshooting documentation
- • Develop prevention measures
Effective troubleshooting capability is an essential skill for AI image creators. Through systematic diagnostic methods, comprehensive solution libraries, and prevention measures, you can minimize the impact of technical issues on your creative workflow.
Remember, every problem solved is an opportunity to learn and improve. Building comprehensive problem records and solution libraries will help you respond to similar challenges more quickly in the future.
