[gpaw-users] The error ZipExtFile when running gapw

[anyy]

Dear all:
After installation of gpaw, I start to test the code but with the
following error. After google a lot I realize that the problem may be
originated from python 2.7. But how to fix it? I have no idea and Could
you give me some suggestions? Thank you!
