Cursors' object has no attribute 'RESIZE_HORIZONTAL' in qt bindings with %matplotlib qt

Question

That is what appears when I run %matplotlib qt.

Along with this error message, I tried widget which gave me the same answer (+ try to use qt). PyQt5 is imported, as well as other packages. Otherwise, when I use %matplotlib inline, I don't have a new window, only the regular graph. Would you be so kind as to answer my question, for best visualisations.
