模块“cv2”没有属性“createThinPlateSplineShapeTransformer”

Question

I'm trying to use the Thin plate shape transformer function.

tps = cv2.createThinPlateSplineShapeTransformer()

However, this error is shown:

module 'cv2' has no attribute 'createThinPlateSplineShapeTransformer'.

I have installed contrib using:

pip install opencv-contrib-python

but the problem is still unsolved. I use opencv 4.5.4 and python 3.8.5

Answer 1

See this issue: https://github.com/opencv/opencv-python/issues/177

It appears that that method has been moved out of the base package. So, you need to install OpenCV with contrib modules. For details, please open the link above.

Answer 2

I fixed this problem using the following commands.

pip uninstall opencv-contrib-python

pip install opencv-contrib-python
