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????

conda activate control
python -m pip install --upgrade pip
pip install gradio

Anyone with a similar error instead #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
