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

[gbaufake]

Hi @serengil,

Is there an issue when analyzing with Yolo v8?

code sample:
analysis = DeepFace.analyze(img, actions=('emotion'), enforce_detection=False, detector_backend=['yolo_, silent=True)

Logs:

2024-02-14 03:48:24,079 [Thread-14 (analyze_video_with_backend)] INFO: {"level": 20, "message": "Detector processed frames", "detector_backend": "yolov8", "processed_frames": 100, "total_frames": 2568}

I could not find anywhere on the code that groups might be used.

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:

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)

Closed with PR - #1038

Thank you @Any-Winter-4079

[gbaufake]

@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 .
