Hey all,<div><br></div><div>I&#39;ve got an older machine that was running cturtle, and just upgraded it to diamondback, and I&#39;ve been getting some very frustrating errors with our rospy-based platform driver. Sample:</div>

<div><br></div><div><div>  File &quot;/home/administrator/ros-clearpath/clearpath_base/src/data.py&quot;, line 108, in pkg_encoders</div><div>    msg = Encoders()</div><div>  File &quot;/home/administrator/ros-clearpath/clearpath_base/src/clearpath_base/msg/_Encoders.py&quot;, line 64, in __init__</div>

<div>    self.header = std_msgs.msg._Header.Header()</div><div>AttributeError: &#39;module&#39; object has no attribute &#39;_Header&#39;</div></div><div><br></div><div>It looks like diamond moved Header from roslib to std_msgs, and I made sure to rosmake --pre-clean this package, but I still seem to be getting this error. The manifest includes the std_msgs dependency.</div>

<div><br></div><div>My PYTHONPATH is /opt/ros/diamondback/ros/core/roslib/src:</div><div><br></div><div>My ROS_PACKAGE_PATH is /opt/ros/diamondback/stacks:/home/administrator/ros-clearpath:/home/administrator/gps_umd</div>

<div><br></div><div>Can anyone see what could be the issue here? Thanks.</div>
