NoneType' object has no attribute 'groups' when using YoloV8 on deepface==0.0.84 about deepface

[Any-Winter-4079]

A hack to solve this:
The weights come from here:
https://drive.google.com/uc?id=1qcr9DbgsX3ryrz2uU8w4Xm3cOrRywXqb

You can download them and put them on your equivalent of this path:
/Users/myself/.deepface/weights/yolov8n-face.pt

Or to be sure, print it in Yolo.py

weight_path = f"{folder_utils.get_deepface_home()}{PATH}"
print(weight_path)

Need detailed exception message please

Normally, exception thrown module and line info should be printed. As I understand, you customize something because these are not standard output of deepface.

When I test that backend as

DeepFace.analyze(img_path=img_path, detector_backend="yolov8")

Then I am having a successful response.

So, your case may be related to the input image you are feeding (share with me if it is not private), or depending on your customization.

That error message should come from regex, and regex is not being used in deepface. You may get it from something different than deepface?

[serengil]

Closed because exception message is not coming from deepface

Here's a bit more information about the error:

@serengil can you release a new version of DeepaFace on Pypi?

[serengil]

I will do it soon, meanwhile you can use the source code as

$ git clone https://github.com/serengil/deepface.git
$ cd deepface
$ pip install -e .
