Looks like you need to install PyQt5 before you can use the Qt5 backend. See here:
https://stackoverflow.com/questions/52346254/importerror-failed-to-import-any-qt-binding-python-tensorflow

Or, you don't use it and use the default TkAgg backend instead: evo_config set plot_backend tkagg

Sorry to bother you. I have configured the PyQt5, matplotlib, numpy and other libraries, but when I try to draw the TUM track, I still have the following problems, I hope to get your help, I am grateful.Thanks...
