Hey, I also encountered the same problem when porting some existing code to the ROS noetic
.
In my case I had a launch
file which invoked rqt_gui
with a so-called perspective file, like this:
<node name="rqt_gui" pkg="rqt_gui"
type="rqt_gui" respawn="false"
args="--perspective-file $(find cyton_gamma_300_gazebo)/config/gazebo_effort_controller.perspective"/>
The perspective file in turn looked similar to the following:
..., "mainwindow": {
"keys": {
"geometry": {
"type": "repr(QByteArray.hex)",
"repr(QByteArray.hex)": "QtCore.QByteArray('01d9d)",
"pretty-print": " : I : I "
},
"state": {
"type": "repr(QByteArray.hex)",
"repr(QByteArray.hex)": "QtCore.QByteArray('000000ff')",
"pretty-print": " Lrqt_topic__TopicPlugin__1__TopicWidget Xrqt_publisher__Publisher__1__PublisherWidget 6MinimizedDockWidgetsToolbar "
}
}, ....
We are interested in the key
-value
pairs looking similar to the following:
"repr(QByteArray.hex)": "QtCore.QByteArray('000000ff')",
and change it to the following:
"repr(QByteArray.hex)": "b'000000ff'",
I.e. after replacing the value with only byte content, like b'000000ff'
and removing QtCore.QByteArray()
creation it launched without errors. Hope this helps!

is able to start without errors. No patching of noetic
code required. Hope this helps!
