module 'cv2' has no attribute 'TrackerKCF_create'

该错误提示表明在使用cv2.TrackerKCF_create()方法时,cv2模块中没有TrackerKCF_create属性。这通常是由于缺少opencv-contrib-python包导致的。要解决此问题,您需要安装opencv-contrib-python包。
安装opencv-contrib-python包的方法如下:
1. 打开终端或命令提示符。
2. 输入以下命令并按Enter键:pip install opencv-contrib-python
3. 等待安装完成后,重新运行您的代码。
请注意,如果您使用的是Python 3.x版本,则应使用以下命令安装:pip3 install opencv-contrib-python
相关问题
recognizer = cv2.face.LBPHFaceRecognizer_create() AttributeError: 'module' object has no attribute 'LBPHFaceRecognizer_create'
这个错误通常是由于OpenCV版本问题引起的。在OpenCV 4.0及以上版本中,创建LBPHFaceRecognizer的方法已经改变,必须使用`cv2.face.LBPHFaceRecognizer_create()`。而在OpenCV 3.x版本中,可以使用`cv2.face.createLBPHFaceRecognizer()`。
你可以通过以下代码检查OpenCV版本:
```
import cv2
print(cv2.__version__)
```
如果输出的版本号是4.0及以上,那么你应该使用`cv2.face.LBPHFaceRecognizer_create()`创建对象。如果输出的版本号是3.x,那么你应该使用`cv2.face.createLBPHFaceRecognizer()`创建对象。
cv2 has no attribute cv_32f
This error usually occurs when you try to use the attribute `cv_32f` with OpenCV's `cv2` module. The reason for this error is that there is no such attribute in the `cv2` module.
To fix this error, you can try changing the attribute from `cv_32f` to `CV_32F`, which is the correct attribute name in OpenCV's Python bindings. Alternatively, you can import the `cv` module instead of the `cv2` module and use the `cv.CV_32F` attribute.
Here's an example:
```python
import cv2 as cv
# create a new image
img = cv.imread('image.jpg')
# convert the image to float32
img = cv.cvtColor(img, cv.COLOR_BGR2GRAY)
img = img.astype('float32')
# apply some filter
img = cv.GaussianBlur(img, (5, 5), cv.CV_32F)
# show the image
cv.imshow('image', img)
cv.waitKey(0)
cv.destroyAllWindows()
```
Note that `cv.CV_32F` is used instead of `cv2.cv_32f`.
