Can you check which packages you have intalled with pip list ? After that you can delete packages with pip:
pip uninstall opencv-contrib-python
Even though you uninstalled opencv-contrib-python, you also need to uninstall other related ones such as opencv-python-headless, opencv-contrib-python-headless packages.
