Importance of Troubleshooting

Encountering various technical issues during AI image generation is inevitable. From model loading failures to unsatisfactory generation results, each problem can affect your creative efficiency and final outcomes.

This guide will provide you with systematic troubleshooting methods and solutions to help you quickly restore normal creative workflows.

Common Problem Categories

Hardware Issues

  • GPU memory insufficient
  • CUDA driver issues
  • High system resource usage
  • Thermal protection activation

Software Configuration Issues

  • Corrupted model files
  • Dependency version conflicts
  • Environment variable errors
  • Permission access issues

Generation Quality Issues

  • Blurry or distorted images
  • Color abnormalities
  • Poor composition
  • Inconsistent style

Network Connection Issues

  • API connection timeout
  • Model download failure
  • Authentication failure
  • Server response errors
System Diagnostic Methods

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

Common Problem Solutions

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
Prevention Measures

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
Emergency Response Process

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
Conclusion

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.
