Dear sir,

I am trying to find the band structure and density of states  of Tio2 by
using the input as given in DFTB+ Recipes. I successfully obtained the file
dftb_out.hsd . After that i issued the command for DOS and i got the errors
as below :

gagan at gagan-desktop:~/tests$ /home/gagan/dptools-0.1p3/bin/dp_dos band.out
dos_total.dat
Traceback (most recent call last):
  File "/home/gagan/dptools-0.1p3/bin/dp_dos", line 8, in <module>
    import numpy as np
ImportError: No module named numpy


kindly give me any solution of this error .
 Thanking You ,
 Yours faithfully,
 Veerpal Kaur,
