How can I solve this?

Answer 1

I have the same issue and fixed in this way In Anaconda installation folder I went to : (change it to your installed path): C:\ProgramData\Anaconda3\Lib\site-packages\PySide2 Edit this file by adding the following code lines :

# below the line 23 type.__signature__
    pyside_package_dir =  os.path.abspath(os.path.dirname(__file__))
    dirname = os.path.dirname(__file__)
    plugin_path = os.path.join(dirname, 'plugins', 'platforms')
    os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = plugin_path

save this file and try again and the issue should be gone :)
