No module named lib.pubsub

[shrx]

I get an error when trying to run this:

Traceback (most recent call last):
  File "RPICameraGUI.py", line 9, in <module>
    from wx.lib.pubsub import Publisher
ImportError: No module named lib.pubsub

Similar here. I get:
Traceback (most recent call last): File "/home/pi/Python/RPICameraGUI.py", line 12, in <module> from wx.lib.pubsub import Publisher ImportError: cannot import name Publisher

I think I fixed the error. It was explained here;
