Steps to reproduce the problem

修改config.txt文件的 key对应value 的路径值为相对路径，以便与其他UI框架共享 checkpoints 与loras,运行后发生错误

Relative paths are supported but the target paths you chose are probably not valid.
Please ensure the path is correct. Keep in mind that you need to use .. for parent directory and . for current directory.

Example:

• Fooocus
  • models
  • config.txt
• stable-diffusion-webui
  • models
    • Lora

"path_checkpoints": ".\\models\\checkpoints",
"path_loras": "..\\stable-diffusion-webui\\models\\Lora",

FYI path_checkpoints and path_loras can both be written in json array syntax as they support multiple paths.
