New in Python. Issue with "six module"

Question

I am trying to run a piece of code for Python in Eclipse in Windows 7 and I am receiving an error.

Traceback (most recent call last):

  File "C:\Users\admin\workspace\New\src\test1.py", line 5, in <module>
    import pylab
  File "C:\Python27\lib\site-packages\pylab.py", line 1, in <module>

  File "C:\Python27\lib\site-packages\dateutil\rrule.py", line 18, in <module>
    from six import advance_iterator, integer_types
ImportError: No module named six

My source code is

import numpy
import matplotlib
matplotlib.use('Agg')
from scipy.cluster.vq import *
import pylab
pylab.close()

# generate some random xy points and
# give them some striation so there will be "real" groups.
xy = numpy.random.rand(30,2)
xy[3:8,1] -= .9
xy[22:28,1] += .9

# make some z vlues
z = numpy.sin(xy[:,1]-0.2*xy[:,1])

# whiten them
z = whiten(z)

# let scipy do its magic (k==3 groups)
res, idx = kmeans2(numpy.array(zip(xy[:,0],xy[:,1],z)),3)

# convert groups to rbg 3-tuples.
colors = ([([0,0,0],[1,0,0],[0,0,1])[i] for i in idx])

# show sizes and colors. each color belongs in diff cluster.
pylab.scatter(xy[:,0],xy[:,1],s=20*z+9, c=colors)
pylab.savefig('/var/www/tmp/clust.png')

I am new to Python and I don't know what the problem could be. I am using Python version 2.7.

Answer 1

You need to install the module six, just use pip install six

If you don't have pip, you can download the package from here, untar the file, change directory cd six-1.7.3 and run python setup.py install

Answer 2

It's simple - you don't have six installed. Install it, for example with pip:

pip install six
