The information of points is put in numpy array.
So, I want to send this numpy array(in python file), which contains a host of (x,y,z), to the other node(in c++ file) using geometry.msg.points display LINE_STRIP of visualization_msgs::Marker.
What type of message should I choose for publishing and subcribling ?
And in which way, I am allowed to convert numpy array to this type of message easily?
