When using vidi3d on Ubuntu, some users will encounter the import error:
ImportError: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found (required by /softdev/akuurstr/python/virtualenvs/emily/lib/python3.8/site-packages/PyQt5/QtGui.abi3.so)
This is usually because there are multiple versions of the QT shared libraries on the system which are incompatible with each other. For instance, if an application installed from apt required Qt5, ubuntu would store the QT shared libraries in:
/usr/lib/x86_64-linux-gnu/
Meanwhile, the PyPI installed PyQt5 stores QT shared libraries in:
<python environment>/lib/python/site-packages/PyQt5/Qt5/lib
The easiest solution to the import error is to ensure that ubuntu only finds PyPI’s shared QT5 libraries by modifying the system environment variable LD_LIBRARY_PATH.
