[ase-users] ASE. Problem with visualisation

[Aleksei]

Hello,

  I am looking at the tutorial " Introduction: Nitrogen on copper" and I 
have got an error when I try to visualise the structure:

run N2Cu.py

I use Ubuntu 16.0 and the last version of anaconda. I installed all 
packages which are required for ASE.

Thank you!
