Im trying to use the stable-diffusion webui with the dreambooth extension on my windows pc, but I keep getting this error

`ImportError: `diffusers` requires transformers >= 4.25.1 to function correctly, but 4.21.0 was found in your environment. You can upgrade it with pip: 'pip install transformers --upgrade'`

but when I use the `pip install transformers --upgrade` command, it says I already have version 4.25.1

Same issue here. It seems it’s a bug or something.

I started having the same issue out of nowhere today as well. I have no clue what I’m doing though so I’m glad I’m not the only one experiencing this. Also my dreambooth extension no longer shows up as a result…is that everyone else’s issue also?

Yeah, having the same. I tried to update the requirements.txt to reflect the higher version but it did not trigger an update when executing the bat…

what version of diffusers is installed? I had to downgrade to 0.9.0 to get my system working today.

Here is the solution, until they’ll come up with some official one, **it is very important to keep tabs consistent and the same!!!** :

1. Open launch.py with text editor  
find this line and the next line:

```auto
xformers = '--xformers' in sys.argv
ngrok = '--ngrok' in sys.argv

```

add this after

```auto
    skipUpdate = '--skip' in sys.argv

```

1. find this line **(skip to point 4 for full code)**

```auto
git_clone(stable_diffusion_repo, repo_dir('stable-diffusion-stability-ai'), "Stable Diffusion", stable_diffusion_commit_hash)

```

add this before it:

```auto
if not skipUpdate:

```

1. find this:

```auto
 if update_check:
            version_check(commit)

```

add after:

```auto
    else:
        print("Skipping updates...")

```

you need to tab everything inside

1. the whole section will look like this (copy and replace this part):

> **Full code after replacement, copy with spaces and tabs!**
>
> ```auto
> if not skipUpdate:
> git_clone(stable_diffusion_repo, repo_dir('stable-diffusion-stability-ai'), "Stable Diffusion", stable_diffusion_commit_hash)
> git_clone(taming_transformers_repo, repo_dir('taming-transformers'), "Taming Transformers", taming_transformers_commit_hash)
> git_clone(k_diffusion_repo, repo_dir('k-diffusion'), "K-diffusion", k_diffusion_commit_hash)
> git_clone(codeformer_repo, repo_dir('CodeFormer'), "CodeFormer", codeformer_commit_hash)
> git_clone(blip_repo, repo_dir('BLIP'), "BLIP", blip_commit_hash)
> 
> if not is_installed("lpips"):
> run_pip(f"install -r {os.path.join(repo_dir('CodeFormer'), 'requirements.txt')}", "requirements for CodeFormer")
>         
> run_pip(f"install -r {requirements_file}", "requirements for Web UI")
>         
> run_extensions_installers(settings_file=args.ui_settings_file)
>         
> if update_check:
> version_check(commit)
> else:
> print("Skipping updates...")
> 
> ```

1. Open this file: modules/shared.py and find this line:

```auto
parser.add_argument("--xformers", action='store_true', help="enable xformers for cross attention layers")

```

add this line bellow

```auto
parser.add_argument("--skip", action='store_true', help="skip updates")

```

1. save everything

2. now open up a cmd window in the stable-diffusion folder and type  
venv\Scripts\activate.bat

3. type this command next:  
pip install transformers --upgrade

4. now lunch webui.bat with argument --skip to skip updates (downgrades) to transformers

It will download some new weights (~2GB), not sure what module is updating, probably dreambooth  
Also --skip will make it start faster, skips downloading/checking for updates

* * *

Edit: Found the updated file  
C:\Users\XXXX.cache\huggingface\hub\models–openai–clip-vit-large-patch14\snapshots\8d052a0f05efbaefbc9e8786ba291cfdf93e5bff\pytorch\_model.bin

Looks like it’s the CLIP model probably updated, not sure

Thanks for this but I am having an issue and my python skills really suck…

```auto
Traceback (most recent call last):
  File "C:\Users\nbock\Documents\AI\stable-diffusion-webui\launch.py", line 238, in <module>
    if not skipUpdate:
NameError: name 'skipUpdate' is not defined

```

But I have added “skipUpdate = ‘–skip’ in sys.argv” in line 197 under ngrok…  
I’d say that variable is defined 😃 but python disagrees :))

Any idea?

Looks like even `venv\Scripts\activate.bat` and `pip install transformers --upgrade` didn’t update transformers. I even tried `pip install transformers==4.25.1` No luck…

It automatically reinstalls it back to previous version during start-up: `Installing requirements for Web UI`

Could you please update the "Installing requirements " scripts of Web UI to not force install a version of `transformers`? Does someone have a link to the “automatic” installation file?

@anton-l is doing a patch release now so that the scripts will work as expected. Should be ready in 1 hour.

In general, though - I don’t think it’s a good idea to force install versions upon launch. The user should IMO have control over the installation of the different versions.

did you actually patched the py files? I’m actually using that locally without any issues, and it starts faster.  
Make sure to launch with skip parameter: webui.bat --skip

If you getting this error on the Stable Diffusion WebUI then it’s because your Dreambooth extension is outdated. You need to run a update on your extensions.

First do a git pull on Stable Diffusion web-gui for good measure.

Then start SD and go to extensions tab and click on Check for Updates button. It will run a check on each extension you have installed. If it’s outdated it will list as “behind” with a ticked tick box.

Now Apply and Restart should restart the web-gui and start the updates but mine didn’t closing the console windows and re-running the bat file to start Stable Diffusion started the update process.
