Ipython matplotlib: ImportError: libQt6Svg.so.6

Hello everyone,

when utilizing ipython, I’m unable to display anything using ipython, it provides me with an error:


1 import sys
      2 import os
----> 3 from IPython.external.qt_for_kernel import QtCore, QtGui, enum_helper
      4 from IPython import get_ipython
      6 # If we create a QApplication, keep a reference to it so that it doesn't get
      7 # garbage collected.

File ~/.local/lib/python3.10/site-packages/IPython/external/qt_for_kernel.py:127, in <module>
    123         return [qt_api]
    126 api_opts = get_options()
--> 127 QtCore, QtGui, QtSvg, QT_API = load_qt(api_opts)
    128 enum_helper = enum_factory(QT_API, QtCore)

File ~/.local/lib/python3.10/site-packages/IPython/external/qt_loaders.py:365, in load_qt(api_options)
    362     continue
    364 #cannot safely recover from an ImportError during this
--> 365 result = loaders[api]()
    366 api = result[-1]  # changed if api = QT_API_PYQT_DEFAULT
    367 commit_api(api)

File ~/.local/lib/python3.10/site-packages/IPython/external/qt_loaders.py:256, in import_pyqt6()
    249 def import_pyqt6():
    250     """
    251     Import PyQt6
    253     ImportErrors raised within this function are non-recoverable
    254     """
--> 256     from PyQt6 import QtCore, QtSvg, QtWidgets, QtGui
    258     # Alias PyQt-specific functions for PySide compatibility.
    259     QtCore.Signal = QtCore.pyqtSignal

ImportError: libQt6Svg.so.6: cannot open shared object file: No such file or directory

Although this command works fine with just python (as does the following plt.show()).

This seems to be a linking problem, but not one that I’ve managed to solve.

Any ideas ?


Just curious, do you have the qt6-svg package installed?
