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

[sudip chakraborty]

Hello everybody
  I am a new user in ASE and it's really optimum according to my
requirement. I have a question regarding the STM study. For getting
stm image can we do without having Gpaw code? I have installed ase
3.4.1. along with numpy and matplotlib also. But while running the
following script I am getting some unusual error of pylab. As a
beginner of Python I am not getting what exactly the problem is. I
will be reall grateful if somebody can illuminate me in this problem.

c = stm.get_averaged_current(4.5)
h = stm.scan(c)
