Biopython not working on Window 7 64 (import bio function not working)

I am having trouble using biopython as my 'import bio' does not work.

I have Window 7 , 64-bit system with Python 2.7.1 with Piston, Django and NumPy site packages installed and they all work well with the import function.

Any ideas?开发者_开发知识库

From the biopython download page.

Note we don't (yet) have official 64 bit Windows Installers - however, Christoph Gohlke has kindly made Windows 64bit installers for NumPy and Biopython (and other tools) available for testing.

Did you install the 32bit package? If so, try uninstalling it and installing the 64bit one.
