AttributeError: 'Slider' object has no attribute 'elem_classes'

[kirintea]

I encountered this problem after updating the project today.
The startup fails.
so I changed the content of scripts.py line529.

if hasattr(comp, "elem_classes"):
# 修改
comp.elem_classes = ["gradio-" + comp.get_block_name(), *(comp.elem_classes or [])]

And the boot was successful? But the UI looks weird.
New problems arise at the same time.

Did you sync the Python GUI?

I got this same error, but not for the same module as this (probably the issue is fixed with the SD repo. If you have the same error as the OP, update to the latest code using git pull in your SD folder.

My error was caused by the dreambooth plugin -- to start my UI, I did the following:

• Go to the extensions folder, take a zip backup of the existing folder ( just for later reference if you want )
• Move that folder out of the extensions folder into some other place on your HDD ( that is not the SD codebase )
• SD will now start without issues

I saw this post on Redit and the person says they were able to reinstall a new(?) dreambooth plugin to get it working... nevertheless the dreambooth

我在Google上查到这个如何修复 Python 中的 AttributeError并用该办法解决了不能运行的问题，但是WEB的UI发生了一些变化（不影响使用）

try: comp.elem_classes = ["gradio-" + comp.get_block_name(), *(comp.elem_classes or [])] except AttributeError: print('No such attribute')

然后会输出20几个 No such attribute...

修改的是scripts.py line529 内容
