PySide6.QtCore DLL load failed



  • I recently installed PySide6 from Python 3.7.6 in windows 7, and after running my script it throws the following error:
    Traceback (most recent call last):
    File "C:\Scripts_Creator\Circular_Progress_Bar\main.py", line 3, in <module>
    from PySide6.QtCore import *
    ImportError: DLL load failed: No se encontrĂ³ el proceso especificado.

    Also the designer.exe throws me the following error from the PySide6 path:
    alt text

    Does anyone know the solution?



  • @diagom02 Recommendation: when you install python check the option that adds the path to the PATH.

    alt text

    So uninstall python and pyside6, install using my recommendation and then install pyside6.

  • @eyllanesc I always do it, even though I already did, should I reinstall it again?



  • That issue occurs with PySide6 versions 6.2.1 and 6.2.0.
    You should uninstall any of these with: pip uninstall PySide6
    From the address below you can download one of previous releases as WHL file (6.1.3 works correctly):
    https://download.qt.io/official_releases/QtForPython/pyside6/

    If downloaded version was 6.1.3, command for new PySide6 installation will be:
    pip install PySide6-6.1.3-6.1.3-cp36.cp37.cp38.cp39-none-win_amd64.whl

    You can check the result in IDLE with:
    import PySide6
    PySide6.__version__

    You should get the following answer:
    '6.1.3'

    Best regards!
