UserWarning: Error while starting the viewer client. #1448

Hi, I'm new to Pinocchio, and I followed the tutorial here. I already got so much help from @nim65s , and I wanna use gepetto-gui to visualize the robot.

  1. What I ran: usr_robot = load('ur5_gripper'). it didn't report error.

tiago_robot = load('tiago', display=True). This report:

In [5]: tiago_robot = load('tiago', display=True)
/opt/openrobots/lib/python3.6/site-packages/pinocchio/robot_wrapper.py:272: UserWarning: Error while starting the viewer client.
Check whether gepetto-viewer is properly started
  self.viz.initViewer(*args, **kwargs)

I followed here to install the gepetto, what I ran is: sudo apt update && sudo apt install robotpkg-py36-qt5-gepetto-viewer-corba And it's successful.

Have I missed something here?

  1. And when I rangepetto-gui, the gui can be launched but I cannot choose robot from file, which is no robot I can choose. I already set the export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/opt/openrobots/share

Thanks in advance.

You should run in another terminal gepetto-gui. Other issues in Pinocchio already mentioned this issue. Next time, please look at the history first. It will be quicker and simpler for everybody.

@jcarpent Hi, sorry to ask this again. I can run the gepetto-gui when I load robot from another terminal. But the second thing I mentioned above:

when I ran gepetto-gui, the gui can be launched but I cannot choose robot from file as this video do, which is no robot I can choose. I already set the export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/opt/openrobots/share

Have I missed something?

Understood, thank you.

@hjw-1014 If you troubles with gepetto-gui, just switch to the Meshcat viewer solution. It is simpler to install and use.

hjw-1014 commented 3 years ago

@jcarpent Thank you very much, I will search Meshchat viewer.
