This solved the error for me.

Hi, I need to import cv2 as well in a project and if i uninstall opencv-python, I can no longer import cv2. Keeping both opencv-python and opencv-contrib-python still shows the same error

versions
opencv-python-4.2.0.34
opencv-contrib-python 1.18.1

uninstall both ("opencv-python" and "opencv-contrib-python" ) and then install "opencv-contrib-python"

[VoNhatVinh]

I uninstall opencv-contrib-python==3.4.14.51 and reinstall it. Works for me!

[AliKJaber]

First, pip uninstall opencv-contrib-python, and then, pip install opencv-contrib-python. Its work fine for me and solved all related Tracker issues.

[Saugatkafley]

Uninstalling the both opencv-python and opencv-contrib-python ==4.5.5.62 and re-installing only the contrib didn't solved the issue ..

[Saugatkafley]

I just downgraded to opencv-contrib-python ==4.4.0.46 and it resolved it.

[SIDDHARTH-S-001]

uninstall opencv-python
uninstall opencv-contrib-python
then do
pip3 install opencv-contrib-python
this worked for me

首先，pip 卸载 opencv-contrib-python，然后，pip 安装 opencv-contrib-python。它对我来说工作正常，并解决了所有相关的 Tracker 问题。

Yes,it also helps me.Thank you.

[ilkin94]

Delete opencv-python and opencv-contrib. Then install opencv-contrib. This worked for me.

[Curious-Utkarsh]

Delete opencv-python and opencv-contrib. Then install opencv-contrib.

tracker = cv2.legacy_TrackerMOSSE.create()

this worked for me.
