Performance Optimization Solutions

针对消费级GPU的显存限制,可通过三级优化策略实现流畅运行:

  • 基础优化::
    1. 强制使用flux-dev-fp8模型(–model_type参数)
    2. 启用显存卸载(–offload参数)
    3. 降低输出分辨率至512×512
  • 中级优化::
    • 减少扩散步骤至20步(–num_steps 20)
    • 关闭xformers优化(增加–disable_xformers)
    • 使用半精度模式(–half_precision)
  • Advanced Optimization::
    1. 采用LoRA微调替代全模型训练
    2. Using the gradient checkpoint technique
    3. 通过HuggingFace的accelerate库实现CPU卸载

实测数据显示:RTX 3060(12GB)通过上述优化可将单图生成时间控制在90秒内,显存占用稳定在10GB以下。
