transform image message via b0

[yuntao]

In my scene, I use two vision sensor to transform image message of the scene via b0, and it work well,
but when I receive these message using python footprint as follow,

Code: Select all

b0.Subscriber(self.b0_node, 'robot_state_image', self.image_callback)
b0.Subscriber(self.b0_node, 'robot_state_image_1, self.image_callback_1)

the shell gives an error saying " [b0_node] error: HB: Context was terminated".
How can I do with the error?
Wishing your help and reply, thank you.

Your sincerely,
Yuntao
