[gradsusr] PyGrADS OK, but python script is not working!

[Wang Jun]

Hello, dear list,

    I have install pygrads successfully on my Ubuntu 11.04 with 
opengrads 2.0.a8.

    When I test the pygrads as
"/http://cookbooks.opengrads.org/index.php?title=Recipe-008:_Using_PyGrADS_to_draw_contours_on_top_of_a_true-color_image_of_the_earth_%28Blue_Marble%29/  
"

    It worked !

    While when I start to use python script as following : *(ts.py*)
/import grads
from pylab import title, savefig
ga = GrADS()
ga.open('model.ctl')
ga.contour('ts')
title('Surface Temperature')
savefig('ts.png')/


  and run it with: _python2.6  ts.py_

  It said:
/
/usr/local/lib/python2.6/dist-packages/grads/gacore.py:42: 
DeprecationWarning: The popen2 module is deprecated.  Use the subprocess 
module.
   from popen2 import popen2
Traceback (most recent call last):
   File "ts.py", line 3, in <module>
     ga = GrADS()
NameError: name 'GrADS' is not defined/


Can anybody tell me what's the problem here and how can I fix it?


Thanks!
Wang Jun
