ModuleNotFoundError: No module named 'mmengine'

[jsmile]

After I install ddtailer in Stable Diffusion WebUI, I start the WebUI. Then cmd console say like below.

Error loading script: ddetailer.py Traceback (most recent call last): File "F:\AI\WebUI\stable-diffusion-webui\modules\scripts.py", line 256, in load_scripts script_module = script_loading.load_module(scriptfile.path) File "F:\AI\WebUI\stable-diffusion-webui\modules\script_loading.py", line 11, in load_module module_spec.loader.exec_module(module) File "", line 883, in exec_module File "", line 241, in _call_with_frames_removed File "F:\AI\WebUI\stable-diffusion-webui\extensions\ddetailer\scripts\ddetailer.py", line 458, in from mmdet.core import get_classes File "F:\AI\WebUI\stable-diffusion-webui\venv\lib\site-packages\mmdet__init__.py", line 3, in import mmengine ModuleNotFoundError: No module named 'mmengine'

How can I fix it ?

mmcv 2.0.0 / mmdet 3.0.0 released. Use 1.7.1 / 2.28.2 release instead. https://github.com/mlhub-action/ddetailer/commit/ab7a8f4c8143b108c5471d343c6c279c02aba23a

I also encountered the same problem, but I still can't solve it with your method

Error loading script: ddetailer.py Traceback (most recent call last): File "K:\StableDiffusionAIGC\stable-diffusion-webui\modules\scripts.py", line 256, in load_scripts script_module = script_loading.load_module(scriptfile.path) File "K:\StableDiffusionAIGC\stable-diffusion-webui\modules\script_loading.py", line 11, in load_module module_spec.loader.exec_module(module) File "", line 883, in exec_module File "", line 241, in _call_with_frames_removed File "K:\StableDiffusionAIGC\stable-diffusion-webui\extensions\ddetailer\scripts\ddetailer.py", line 458, in from mmdet.core import get_classes File "K:\StableDiffusionAIGC\stable-diffusion-webui\venv\lib\site-packages\mmdet__init__.py", line 3, in import mmengine ModuleNotFoundError: No module named 'mmengine'

I'm sorry. I just a Stable Diffusion user and don't know Python. I would like that someone solve this problem.

[ahang39]

just

cd .\venv\Scripts
activate
pip install mmdet==2.28.2

[kkoib]

I found a solution to my problem Just delete the two files and download the plugin again

1. First delete the mmdet folder in the installation directory F:\AI\WebUI\StableDiffusionAIGC\stable-diffusion-webui\models\mmdet
2. Then delete the plug-in dddetailer folder F:\AI\WebUI\StableDiffusionAIGC\stable-diffusion-webui\extensions\dddetailer
3. Go to github to download the plugin again https://github.com/dustysys/ddetailer.git

[aarrre]

just

cd .\venv\Scripts
activate
pip install mmdet==2.28.2

I tried this instead, works for me. Try running python -m pip install mmdet==2.28.2 instead of pip install mmdet==2.28.2

[jsmile]

I wrote your cmd commands like below :

cd .\venv\Scripts activate pip install mmdet==2.28.2

cd .\venv\Scripts activate python -m pip install mmdet==2.28.2

But window cmd console says the same error, too. Both occure the same result.

Forced the 2.28.2 install with mim instead of pip

mim install mmdet==2.28.2

Worked for me

Ok I fixed it by basically combining all of these solutions lol

First go to to > stable-diffusion-webui\venv\Lib\site-packages (Or in other words, the base SD folder, then venv folder, Lib folder, and site-packages folder Then delete these folders regardless of what the numbers are (in place of x.x.x) _mmc mmcvfull-x.x.x.dist-info mmdet mmdet-x.x.x.dist-info

THEN Go to stable-diffusion-webui\extensions\ddetailer\ddetailer\scripts (The SD extensions folder, and ddetailer folder, then scripts)

There you'll find -> ddetailer.py Open it with either Visual Studio, Notepad++, or just regular Notepad doesn't really matter

Find these lines of code

        run(f'"{python}" -m pip install -U openmim', desc="Installing openmim", errdesc="Couldn't install openmim")
        run(f'"{python}" -m mim install mmcv-full', desc=f"Installing mmcv-full", errdesc=f"Couldn't install mmcv-full")
        run(f'"{python}" -m pip install mmdet', desc=f"Installing mmdet", errdesc=f"Couldn't install mmdet")

and replace them with

        run(f'"{python}" -m pip install -U openmim==0.3.7', desc="Installing openmim", errdesc="Couldn't install openmim")
        run(f'"{python}" -m mim install mmcv-full==1.7.1', desc=f"Installing mmcv-full", errdesc=f"Couldn't install mmcv-full")
        run(f'"{python}" -m mim install mmdet==2.28.2', desc=f"Installing mmdet", errdesc=f"Couldn't install mmdet")

(Thanks to @sumof2primes for this part, and @Oculi-Inverti for the idea of using mim) Not sure if you can't just use pip for mmdet anyway? But this works regardless

and that's all.

Make sure to delete the folders in venv first or the working files won't download to replace them, at least they didn't for me

I have done all the fixes that are given above which solved the issue but brought about another one. Now it is "No module named 'mmdet.evaluation'".

Tried all the proposed solutions here, this is the only one that works. But I didn't want to delete the extensions\ddetailer folder, so I just activated the environment and manually ran these three install commands before launching WebUI.

On MacOS(Apple Silicon), ./venv/bin/pip install mmdet==2.28.2.
