"RuntimeError: Couldn't determine Stable Diffusion's hash" when installing

[HeavenlyChorus]

Getting stuck at this when trying to setup everything with webui-user.bat. Any idea what's potentially causing it?

I have a similar issue. Everything worked fine yesterday. I've tried a clean install of the repo, but it didn't help.

I installed from scratch just now, couldn't reproduce. Do custom models work?

its working fine if i manually install everything and run with python webui.py --precision full --no-half --medvram just a bit less convenient (having to type everything) and also wondering why this happens :P

It doesn't even get to loading models, it breaks right after you launch "webui" file. Another curious thing is when I run "python webui.py" I get the following error:

C:\Files\StableDiffusion\stable-diffusion-webui_>python webui.py
Traceback (most recent call last):
  File "C:\Files\StableDiffusion\stable-diffusion-webui_\webui.py", line 10, in <module>

    import torch
ModuleNotFoundError: No module named 'torch'

But if I launch "webui-user" file, everything works fine, and I can generate images as usual.

[HeavenlyChorus]

ModuleNotFoundError: No module named 'torch'

make sure you are in the venv when doing python webui.py for example, open a python file inside the directory in vscode and select the right python interpreter (bottom right) for it to take effect

That's what you're supposed to do, thats what everybody does usually.

If you set your python path in webui-user.bat will that allow you to run by clicking?

[theunit187]

That's what you're supposed to do, thats what everybody does usually.

Oh, the documentation is somewhat confusing then, in wiki it says: "The installation is finished, to start the web ui, run: python webui.py", and I assumed we work with "webui" files. And it worked fine yesterday, but not today. I'll stick to "user" file then, thanks for clarifying.

make sure you are in the venv when doing

Ah, I see, thanks.

[HeavenlyChorus]

hmm no? the thing that's not working is that it's failing comparing the hashes from what i can tell. and no adding the python path didn't do anything, still the same error.

[BrutalCrabbo]

I've encountered this hash issue too(webui-user.bat updates taming-transformer even though it's already the latest and says its hash is unidentifiable), thus can't initiate the web-ui browser with webui-user.bat. The thing is, you can solve this problem just by reverting the launch.py to the previous version (2nd October).Generating images seems fine, but no guarantee it won't break something.

[Swah]

I found out that for me the problem was my GIT environment variable wasn't defined, which wasn't a problem before as I manually installed dependencies. In webui-user.bat, I now have this line set GIT=C:/Users//.conda/envs/qwe/Library/mingw64/libexec/git-core\git.exe

If you're not sure where your own GIT is installed, you can run "git --exec-path" and add "git.exe" at the end.

Thanks for replying, but still cant get the latest version working.

[CryUshio]

I tried to modify the launch.py and it works.

-   stable_diffusion_commit_hash = os.environ.get('STABLE_DIFFUSION_COMMIT_HASH', "69ae4b35e0a0f6ee1af8bb9a5d0016ccb27e36dc")
+   stable_diffusion_commit_hash = os.environ.get('STABLE_DIFFUSION_COMMIT_HASH', "45bf9a6264b3507473e02cc3f9aa36559f24aca2") # Use latest commit hash

[agarzon]

Having the same error

[Promisin]

In my case, after running launcher.py, I can find files in the corresponding directory. It seems the only problem is that the command can't get right returncode. So I just ignore this case by adding some code in launcher.py. Now everything just work fine. But you should make sure all the thing right except the returncode.

# you can find this code in line 24
if result.returncode != 0 and result.returncode != 1:

[Teale001]

maybe you can upgrade your git version to 2.39.0

[iAimFoxZ]

I just reinstalled Git (https://git-scm.com/download/win) here's a link, and it works just fine

[jmt33]

modify the launch.py

def git_clone(url, dir, name, commithash=None): # TODO clone into temporary dir and move if successful

# if os.path.exists(dir):
#     if commithash is None:
#         return

It's too much of a mystery, but this may have fixed it.

However, I also tweaked launch.py at the same time and was able to get the commit hash from none. However, I was still unable to launch, so I reverted the launch.py changes, but for some reason, the commit hash was still available. So it launched just fine. It's a mystery.

[Foul-Tarnished]

modify the launch.py

if commithash is not None:

still have the issue

[Foul-Tarnished]

I changed git\cmd\git.exe to git\git-cmd.exe

now it's stuck on

venv "F:\SD-WebUI\stable-diffusion-webui\venv\Scripts\Python.exe"

[NielsGx]

I used git\cmd\git.exe

Should be git\git-cmd.exe

After a reinstall of git and changing that, plus a restart, it works

[Promisin]

A new resolution for me Open a brand new Command Prompt, if you can see some error information such as "The system cannot find the path specified" without running any command, you should check Computer\HKEY_CURRENT_USER\Software\Microsoft\Command Processor item in regedit. Then disable or delete the value of Autorun. result = subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True, env=os.environ if custom_env is None else custom_env) shell=True will run the command with the default shell which specific by environment variable COMSPEC in windows, and usually this refers to the cmd.exe. Thus, subprocess.run will receive the error message of Autorun.

[dongxiaofu]

Can you get the latest hash when you run the command git -C repositories\stable-diffusion rev-parse HEAD directly?If not,mybe the version of your git is too low to support the command git -C.My git version is 1.8, and I came across the same error as yours.When I update my git to 2.19.0,it works well,no error.

[ElchWiesel]

Check in the properties of the folder under "security" if users have access. Worked for me after granting access.

[leeruibin]

If someone tries to use pycharm to debug the launch.py and meet this issue again, here is a solution for me. This script call "subprocess.run()" to run the git command. I check the subprocess.run() with git command and find this error may be caused by the wrong os environment.

result = subprocess.run(command, shell=True, env=os.environ if custom_env is None else custom_env)

As shown in this line, it may use os.environ to get the environment variables, but the output variables are not the same as my environment, I use windows 10. You can check whether this varibles are the same as your system variables. For me, the path of git miss, so I modify this script and add the path to my git. Then the issue is solved.

Here is the reference. In run function, add the git path to the os.environ['PATH']

def run(command, desc=None, errdesc=None, custom_env=None, live=False):
    if desc is not None:
        print(desc)
    env_list = os.environ
    cur_path = os.environ['PATH']
    cur_path += ";path to your git bin file" # for example D:\\software\\Git\\cmd
    os.environ['PATH'] = cur_path
    if live:
        result = subprocess.run(command, shell=True, env=os.environ if custom_env is None else custom_env)
        if result.returncode != 0:
            raise RuntimeError(f"""{errdesc or 'Error running command'}.
Command: {command}
Error code: {result.returncode}""")

        return ""

[xiejibing]

update git version to 2.x.

[Tiro00]

hi any fix or advise pls

[zdxpan]

This because a bug of git version, when i use git version 1.8.3.1 it`s not support git -C "path_dir", while it shoud be git -c

change the code launch.py "-C" to "-c" can solve this problem

addition: git -c "/home/dell/workspace/stable-diffusion-webui/repositories/stable-diffusion-stability-ai" rev-parse HEAD can get the repo`s commit Hash

[webgoto]

I edited launch.py in windows. current_hash = run(f'"{git}" -C "{dir}" rev-parse HEAD', None, f"Couldn't determine {name}'s hash: {commithash}").strip() It worked when I changed "{git}" to {git} used in these codes.

[linshizuowei]

I tried to modify the launch.py and it works.

-   stable_diffusion_commit_hash = os.environ.get('STABLE_DIFFUSION_COMMIT_HASH', "69ae4b35e0a0f6ee1af8bb9a5d0016ccb27e36dc")
+   stable_diffusion_commit_hash = os.environ.get('STABLE_DIFFUSION_COMMIT_HASH', "45bf9a6264b3507473e02cc3f9aa36559f24aca2") # Use latest commit hash

this works for me
