Error in the function "utils.google_utils.attempt_download"

[PoissonChasseur]

I just downloaded the latest code from the main branche and when I try to simply run the code with the usage of the webcam with:

python detect.py --source 0

I got the following error message:

(yolov5) C:\Users\vincentrm\D\Obj_detection_Yolo\yolov7-main>python detect.py --source 0

During handling of the above exception, another exception occurred:

When I manually try the link the code is trying to use: https://api.github.com/repos/WongKinYiu/yolov7/releases/latest

I can see why there is this error message since I am seing this:

{
  "message": "Not Found",
  "documentation_url": "https://docs.github.com/rest/reference/repos#get-the-latest-release"
}

Does anyone know how to solve this ?

I made a temporary correction by simply changing line 30 of the "utils.google_utils.py" file by defining:

tag = 'v0.1'

instead of

tag = subprocess.check_output('git tag', shell=True).decode().split()[-1]

Since the pre-trained model files are currently placed in: https://github.com/WongKinYiu/yolov7/releases/tag/v0.1

However, a better solution (which would also be able to handle future tags) would be much better.

Also, at line 28 of the "utils.google_utils.py" file with the following code:

            assets = ['yolov7.pt', 'yolov7-tiny.pt', 'yolov7x.pt', 'yolov7-d6.pt', 'yolov7-e6.pt', 
                      'yolov7-e6e.pt', 'yolov7-w6.pt']

It's missing all cases with "_training" (which seem to be the ones to use for "transfer learning", based on the README), so it looks like this line should be changed to something like this:

            assets = ['yolov7.pt', 'yolov7-tiny.pt', 'yolov7x.pt', 'yolov7-d6.pt', 'yolov7-e6.pt', 
                      'yolov7-e6e.pt', 'yolov7-w6.pt', 'yolov7x_training.pt',
                      'yolov7-e6_training.pt', 'yolov7-e6e_training.pt', 'yolov7-d6_training.pt',
                      'yolov7-w6_training.pt', 'yolov7_training.pt']

Why is there no yolov7-tiny_training.pt? Is there a problem with using the non-transfer-learning yolov7-tiny.pt instead?
