DLL load failed while importing QtWebEngineWidgets:

Hi! I have created an environment in conda, installed thy phy in there, but I still cannot open the template gui. I always get the following error. Uninstalling and reinstalling of the QtWebEngineWidgets doesn’t help. Could you help me to solve the problem? Thanks!

A colleague had the same problem which we were able to fix:

pip uninstall PyQt5 pip uninstall PyQt5-sip pip uninstall PyQtWebEngine

pip install --upgrade pyqtwebengine==5.12 pip install --upgrade pyqt5==5.12.3

(the specific versions listed above were the lowest ones pypi was offering at the time)

You may need to manually remove the PyQt folders in Lib\site-packages and repeat the above steps but we didn’t need to.
