The node is informing you that there is no subscriber for your markers. Just open RVIZ, and add the markers. If there is a subscriber, the basic_shapes node is going to start to publish the markers.

How do we add markers after opening RViz? It also says that no tf data , Actual error no FIXED Frame exists

in my case, it seems the forward slash in "/my_frame" causing this problem. Just remove it and in rviz type "/my_frame" in Fixed Frame and add Marker by clicking on Add button.
