[Bug]: AttributeError: 'NoneType' object has no attribute 'lowvram'

[TinyHaHa]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

Steps to reproduce the problem

I run the run.bat, the text showcased "Stable diffusion model failed to load" , "AttributeError: 'NoneType' object has no attribute 'lowvram'"

What should have happened?

i am a rookie, i think it will run but not this error.

What browsers do you use to access the UI ?

assuming that you're not using Dev or RCbranch

based on this message
Stable diffusion model failed to load

as you do not post the entire logs so I can't be sure but essentially what most likely happen is that your model is corrupted during download and so the model failed to load

they're existing issue that if the model that the WebUI tryies to load on startup is corrupted
then the UI would fall into a loop of not able to load or switch any other models
this issue has been fixed

• Fix corrupt model initial load loop #15600

also in the next release of web UI when it also downloads a model it will check for its integrity

• Initial model download integrity #15602

---

what you have to do
you should delete the corrupt model

after deletion you an relaunch the UI
if theres is no model present webui automatically downloads the default sd1.5 model for you
you could also download a model you actually want to use manually and place it in the directory, this way it dosen't waste time downloading a model that you probably won't use

downloading a model manually is especially recommended if you have bad internet

1. i download the following assets:
   

2. as the guideline i tried again:
   (1)Download sd.webui.zip from v1.0.0-pre and extract its contents.
   (2)Run update.bat.
   (3)Run run.bat.

3.with all the steps above:

finally, the last question i cannot solve:

I'm suspecting auto download always fails on your internet
like I mentioned above

downloading a model manually is especially recommended if you have bad internet

you can download the default 1.5 modul using the link below
webpage
https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/v1-5-pruned-emaonly.safetensors
direct download link
https://huggingface.co/runwayml/stable-diffusion-v1-5/resolve/main/v1-5-pruned-emaonly.safetensors

or you could find a model (checkpoint) you like on sites like https://civitai.com

[TinyHaHa]

thanks, i have download the module from the direct donwload link, would you please tell me how to do the next? is that i should use the new file to cover or insert into any file? Or i should run the new download file directly?

[Cupid-ljy]

It is possible that the model is damaged. Extract the model and reload it. But I don’t know how to check which model has a problem.
