[Numpy-discussion] Problem with importing numpy in Ubuntu

I'm getting the same

>>> sys.maxunicode
65535

I might have some "hand complied" python. Once I compiled Biopython long
ago.

The problem is I do not know how to clean up all the python version that I
have. I tried the reinstall option. It does not work. I cannot remove the
python. It will wipe out my operating system.

Any suggestion?
