ValueError: insecure pickle string

[pradeepbpin]

I am encountering 'Value Error: insecure string pickle' when trying to
execute the script on Ubuntu. The same script and the pickled file
works without any problem in Windows. For working in Ubuntu I just
copied both the script file and pickled file from Windows.


How can I get out of this error? Rather, I would like to have common
script and pickled file that can work platform independently.
