ERROR: get_pose_vector()

[DiogoFerreira77]

Hi, I was trying to replicate this using URSim. However, when the camera opens it crashes but there is not shown no error. So I tried to run the code without the use of a camera where I gave one value for the face_position and I found that the error is due to the function move_to_face, more precisely at line 325 (oriented_xyz_coord = oriented_xyz.get_pose_vector()) .

I don't understand where this came from, in the URBasic module there is no function called like that. How can I solve this?

The following image shows the error when I put one value for center of the face:

UPDATE: I uninstalled math3d library and installed via here.

If I do the same, i.e, I give one value of the center of the face it runs well (see results in the following image) however, when I use the camera it crashes. An window pops up and closes immediatly. What could it be?

PS: With the pc's webcam works but the robot does not move. With a GigE camera is when it crashes.
