Import the needed modules
import tf2_ros
import tf2_geometry_msgs
Initialize the tf buffer and listener somewhere in your init function
tf_buffer = tf2_ros.Buffer(rospy.Duration(1200.0)) #tf buffer length
tf_listener = tf2_ros.TransformListener(self.tf_buffer)
Do the actual transformation
transform = tf_buffer.lookup_transform(target_frame,
pose_stamped_to_transform.header.frame_id, #source frame
rospy.Time(0), #get the tf at first available time
rospy.Duration(1.0)) #wait for 1 second
pose_transformed = tf2_geometry_msgs.do_transform_pose(pose_stamped, transform)
