Unable to correctly install scepter with ComfyUI

[aaaron7]

With Python 3.12, I can correctly install the Node, but get error "ImportError: cannot import name 'find_loader' from 'importlib'" when running the workflow.

With Python 3.10, Can't install the plugin because only aliyun-sdk-core(2.13.10) can be installed, but scepter requires minimum version 2.13.12.

@aaaron7 You can try used python 3.10.15 to install.
