Error: from sqlalchemy import exceptions as sqla_exceptions-> ImportError: cannot import name exceptions -> cannot start childsplay application in Kubuntu 14.04

I am using Kubuntu 14.04 in my computer and I installed Childsplay, but it does not get opened.
The terminal output as follows:-

mallick@mallick-desktop:~$ childsplay
Traceback (most recent call last):
  File "/usr/games/childsplay", line 118, in <module>
    import childsplay_sp.SPMainCore as SPMainCore
  File "/usr/lib/python2.7/dist-packages/childsplay_sp/SPMainCore.py", line 64, in <module>
    from sqlalchemy import exceptions as sqla_exceptions
ImportError: cannot import name exceptions
mallick@mallick-desktop:~$

Please help,
Thanking you,
