Thanks for the clarification.
I agree with your view. In fact the ocropus project is based on ubuntu
12.04(64bit)which uses python 2.7.3 works fine.

Tom,Creator of ocorpus project has already in advance  clarified that he
support *only 12.04* and *not* *12.10 *version -since he has no
plan/interest  to support for ubuntu 12.10 for ocropus project work.

Due to my curious to know whether ocorpus works fine in ubuntu 12.10 which
has python version 2.7.3 also(similar to ubuntu 12.04) - but unfortunately
failed in my experiment as already reported reason to you.

In the circumstances, I have to use *only ubuntu 12.04(64 bit)* and  may
have to *uninstall the ubuntu 12.10* since it appears that python 2.7.3  of
ubuntu 12.10 does not support Ocropus project due to *some inherent
problem*in the ubuntu 12.10 or installed python 2.7.3 in the ubuntu
12.10 itself -
which I don't know..

If you do research as to why python 2.7.3 installed in ubuntu 12.10 does
not work on the lines of ubuntu 12.04(64bit) which has *same version of
python* viz. 2.7.3, it will be benefited users like me  I am feeling that I
may not get support from you,I decided to discontinue usage of  new version
ubuntu 12.10.
