模型下载问题排查指南
遇到fetch_model下载失败时可尝试：
- Checking the network environment：确保能访问ModelScope服务器(测试ping www.modelscope.cn)
- manual download: Accessed via browser
https://modelscope.cn/models/<模型路径>下载后指定本地路径 - 参数验证：确认revision参数有效性(如20240902173035)
- Proxy Settings：境外用户可能需要配置HTTP_PROXY环境变量
备用解决方案::
model_path = "/本地路径/flux1-dev-with-vae.safetensors"
config = FluxModelConfig(dit_path=model_path)
如持续失败，建议检查：
- 磁盘剩余空间(建议保留20GB+)
- Python版本(需≥3.8)
- SSL证书有效性(更新certifi包)
