2018-04-21 23:16:30 -0500 | marked best answer | Why give me this error? AttributeError: 'int' object has no attribute 'a' Hi, I need create a node, this node must be Subsriptor and Publicator. But, I have this error. My code is this: I modified package.xml and CMakeList.txt, as the tutorial of "msg" explain. I hope, any answer. Thank You Edit: Thanks, for your answer. Effectively, my error is in python. I need to use the value of the variable "a and b" of the callback and callback2 function, in the listener function. But first, I got an error: "global name" xx "is not defined", so I declared them at the beginning of the program. But it does not work. I need those variables to publish them through a topic to another node. In this node, I need receive and send variables. I don´t know, if this lines are good. m and n values are the variables that I need call of the callback function. I would appreciate if you helped me with that. |
