Could you please help me figure out why I'm getting this error when I run python gradio_canny2image.py as soon as I hit run of the UI????

Anyone with a similar error instead https://github.com/lllyasviel/ControlNet/issues/492 . In this case there is no error message. Just loading forever

我一开始遇到的问题是点击run没反应，然后就关闭浏览器再打开在上传图像出现楼主一样的错误，后来更新一下gradio没反应，最后干脆指定版本3.38.0，解决了

pip install gradio==3.40.1 solved it for me

I got the same problem too. And I have tried to change gradio version in original 3.16.2, 3.38.0, 3.40.1, and the latest 4.29.0, but none of them works. It can running but showing error in webUI in gradio 3.16.2, 3.38.0, 3.40.1. But totally cannot work in the latest 4.29.0, with "typeerror: init() got an unexpected keyword argument 'socket_options'". May I ask does anyone have the same problem and know hwo to solve it? I guess it is still about the gradio version, and does anyone knows how can we find the appropriate version? Thank you!

pip install gradio==??? might have solved the problem, but it took too long for the pip version solver to solve. The following loosy got me a quick resolution.

pip install "gradio>=3.38.0,==3.*"

pip install gradio==3.50.1 worked for me.
