ImportError: dynamic module does not define module export function (PyInit__tf2) #21

I am trying to launch the simulation in gazebo. The compilation phase went well but during launch I keep getting the following error

ImportError: dynamic module does not define module export function (PyInit__tf2)

And here is the complete output. Kindly let me know if any solution is available thanks.

Errors like this are caused by python version problem. Your tf package can only be used by python2, so just change the first line of your spawn_model script: from #! /usr/bin/env python to #! /usr/bin/env python2.7.

It works? I tried to change spawn model script, but simulation still has error above.
