seems qt is not installed properly. try conda install qt or re-create env with conda create -n new_env python=3 qt pyqt pyside2 -y

edit:

correct to conda create -c conda-forge -n new_env python=3.9 qt pyqt pyside2 -y

What worked for me without using conda:

pip install pyqt5
pip install qtpy

I got the same error. When I tried to run 'labelme' in terminal, this error appear:

In case someone meet the conda pyside2 PackageNotFound error, please add conda-forge channel

conda create -c conda-forge -n new_env python=3 qt pyqt pyside2
