"ModuleNotFoundError: No module named 'imgui'" (Windows 10)

[AlexxB31]

"py visualizer_drag.py" there is an error: "ModuleNotFoundError: No module named 'imgui'"
and menetioned before " line 15, in "
When I look into the visualizer_drag.py I can see there should be imported "imgu" whatever it is.
I have installed for many hours everything (python, pip, torch, anaconda/conda etc.) and double-checked.
Please advise me how this can be solved.

pip install imgui
