qt_gui_main() found no plugin matching "rqt_image_view/ImageView"

[rohitspace]

Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available:
Traceback (most recent call last):
File "/opt/ros/noetic/lib/python3/dist-packages/qt_gui_cpp/cpp_binding_helper.py", line 43, in

qt_gui_main() found no plugin matching "rqt_image_view/ImageView"
try passing the option "--force-discover"

Also, rqt --list-plugin does not show image_view even though its installed

I am facing the same issue here

Progress on this?

Edit: make sure you uninstall all possible libraries associated with Qt (including separate python versions), rqt_image_view can also be rendered using PySide2. That’s what fixed it for me.
