As you said, the error seems to be connected to your Python. ROS Kinetic only works with Python 2.7. Can you try running following command and sharing outputs?
python -c "import tf"and
python2.7 -c "import tf"It will show if you can correctly import tf library.
Hi ,i am sorry to bother you. i use your airsim_ros_client pubImages.launch. And then it occurs this error
