Error using rqt_graph - ImportError: dynamic module does not define module export function (PyInit_libqt_gui_cpp_sip)

[liamreneroy]

Im using ROS Melodic and Ubuntu 18.04.
CONDA_PYTHON_EXE=/home/parallels/anaconda3/bin/python
ROS_PYTHON_VERSION=2
PYTHONPATH=/home/parallels/catkinws_melodic/devel/lib/python2.7/dist-packages:/opt/ros/melodic

Whenever I run rqt_graph or any other rqt I get the error:

Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available: Traceback (most recent call last): File "/opt/ros/melodic/lib/python2.7/dist-packages/qt_gui_cpp/cpp_binding_helper.py", line 43, in from . import libqt_gui_cpp_sip ImportError: dynamic module does not define module export function (PyInit_libqt_gui_cpp_sip)
