OPENCV跟踪器未识别（AttributeError：Module＆＃x27; CV2;没有属性＆＃x27; trackerkcf_create;）
import cv2
if __name__ == "__main__":
major_v, minor_v, subminor_v = (cv2.__version__).split('.')
# >>> 4.6.0
tracker = cv2.TrackerKCF_create()
# >>> AttributeError: module 'cv2' has no attribute 'TrackerKCF_create'
如上所述，运行时，这些是我得到的结果（我已经与CV2中的其他跟踪器一起尝试过，除trackermil_create外，所有应该包括的跟踪器都给我带来了这个错误。我用过 pip安装opencv-python， pip install opencv-contrib-python和 pip安装opencv-contrib-python-headless 在我的终端上尝试安装OpenCV。我没有遇到CV2属性的任何其他问题（例如imread，imshow，resize），但是跟踪器给我带来了困难时间，我想知道我从一开始就做错了什么。谢谢。

tracker = cv2.TrackerKCF_create()

As the code above shows, when running this these are the results I get (I have tried this with other trackers in cv2 and other than TrackerMIL_create all trackers that are supposed to be included are giving me this error. I usedpip install opencv-python,pip install opencv-contrib-python, andpip install opencv-contrib-python-headless
on my terminal to try and install opencv. I haven't run into any other issues with cv2 attributes (such as imread, imshow, resize) but the trackers are giving me a hard time and I was wondering if there is anything I am doing wrong from the start. Thanks.

删除所有内容，然后重新安装
opencv-contrib-python。这些软件包可能会相互冲突。pip卸载opencv-contrib-python opencv-python opencv-contrib-python-headless＆amp; PIP安装opencv-contrib-pythonRemove everything and then reinstall
opencv-contrib-python. The packages can conflict with one another.pip uninstall opencv-contrib-python opencv-python opencv-contrib-python-headless && pip install opencv-contrib-python与@ddelarue的答案一样，您要确保您已安装了
opencv-contrib-python（或opencv-contrib-python-headless），而不是非contrib版本。此外，在某个时候，API已更改。现在是
cv2.trackerkcf.create（）（在4.9.0.80中，也可能是更早的版本）As with @ddelarue answer, you neeed to make sure that you have
opencv-contrib-python(oropencv-contrib-python-headless) installed and not the non-contrib versions.In addition, at some point the API was changed. It is now
cv2.TrackerKCF.create()(in 4.9.0.80, and potentially earlier versions too)
