Dear all,
while analysing the ied results obtained from gromacs, in order to start
the ied, we need to start pyhton. but when i type gopython in the vmd
(1.8.6) console,
the meassge is like this...

vmd > gopython
Info) Starting Python...
'import site' failed; use -v for traceback
Could not find Numeric Python version >= 22.0
ImportError: No module named numeric_version
Info) Text interpreter now Python
Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "/usr/local/lib/vmd/scripts/python/", line 62, in ?
    from types import *
ImportError: No module named types

>>> import vmdnumpy, Numeric
Traceback (most recent call last):
  File "VMD", line 1, in ?
ImportError: No module named vmdnumpy

i have installed the python library from the vmd website... Can any one
suggest me any solutions.
