[ase-users] having 'pylab' problem in STM study

[Marcin Dulak]

Hi,

it's seems that you have installed dateutil package that requires python 
 >= 3.0 (http://niemeyer.net/python-dateutil), or it's just a bug in 
dateutil.
It's always better to use the package that comes with you Linux 
distribution, and as a rule to never install packages manually
(from tarballs or python eggs) as root.

Best regards,

Marcin
