Questions about move_IT running on Windows

edit

I set up ros and MOVE_IT packages on my Windows system.I then tried to run the Python interface section of the MOVE_IT tutorial.Then I encountered two problems: first, I couldn't load Rviz properly when I run roslaunch panda_moveit_config demo.launch and encountered the following error:

 QObject::connect: Cannot queue arguments of type 'QVector<int>'
(Make sure 'QVector<int>' is registered using qRegisterMetaType().)
QObject::connect: Cannot queue arguments of type 'QVector<int>'
(Make sure 'QVector<int>' is registered using qRegisterMetaType().)

My RVIz screen is a black screen. second ,I Tried to run rosrun moveit_tutorials move_group_python_interface_tutorial.py .and I got following result:

[rosrun] Couldn't find executable named move_group_python_interface_tutorial.py

I want to know how to run python file on windows ros. p.s. I Tried to load my own robot in rviz and I got success.
