OpenCV AttributeError模块'cv2.cv2‘没有属性'Tracker_create’
提问于 2019-11-18 20:08:17
我试图运行这段代码，但得到了一个属性错误。任何帮助都将不胜感激。

这取决于您安装的OpenCV包和版本。
我相信你需要OpenCV 3.4+来运行这些模型。一些跟踪器型号在3.2和3.3中可供使用。您的脚本中的所有跟踪器都可在3.4中使用
OpenCV包：opencv-python：这个存储库包含OpenCV库的主要模块。
opencv-contrib-python：opencv-cont肋骨-python存储库包含两个主要模块以及cont肋骨模块。
python -m pip install opencv-contrib-python，检查一下是否有3.4+和pip show opencv。
有关更多细节，请参见如何安装opencv
更新
正如@ some 48956所指出的那样，opencv v 4.5.x已经将其中一些算法转移到了cv2.legacy。例如，访问TrackerMOSSE_create函数。你必须从cv2.legacy.TrackerMOSSE_create那里得到它。
我建议与opencv GitHub保持同步，因为一些函数/算法可能会移动或被删除。

如果您使用的是OpenCV 4或更高版本，那么上述代码可能无法工作。
if int(minor_ver) < 3:OpenCV 4的换行 您只需为这项实验安装opencv控制装置。
包含
pip install -r requirements.txt
requirements.txt
dlib==19.19.0
imutils==0.5.3
numpy==1.18.4
opencv-contrib-python==4.2.0.34
scipy==1.4.1修改后的代码，与OpenCV 4版本兼容

我收到了一个错误：tracker = cv2.TrackerMOSSE.create()
甚至以为我已经安装好了:opencv-cont肋骨-python
我能够通过使用以下方法来修复错误：tracker = cv2.legacy_TrackerMOSSE.create()
