'ImportError: no module named pytz' when trying to import pylab?

As far as I can tell, I don't even need pytz for what I'm doing.

I retrain python for image processing using O'Reilly's book "Programming Computer Visions with Python" to work (and I'm also new to Mac, so for both points I apologize if this is a stupid question). Along with the image 'empire.jpg', I'm trying to run a script on page 16 that looks like this:

from PIL import Image from pylab import * # read image to array im = array(Image.open('empire.jpg')) # plot the image imshow(im) # some points x = [100,100,400,400] y = [200,500,200,500] # plot the points with red star-markers plot(x,y,'r*') # line plot connecting the first two points plot(x[:2],y[:2]) # add title and show the plot title('Plotting: "empire.jpg"') show()

but I get the following output with an error:

  File "plotch1.py", line 2, in <module> from pylab import * File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/pylab.py", line 1, in <module> from matplotlib.pylab import * File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/pylab.py", line 208, in <module> from matplotlib import mpl # pulls in most modules File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/mpl.py", line 4, in <module> from matplotlib import axes File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/axes.py", line 18, in <module> from matplotlib import dates as mdates File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/dates.py", line 82, in <module> import pytz ImportError: No module named pytz

I am using OS X 10.9.4. I installed matplotlib and numpy from macpython.org and I installed scipy 0.11.0 for python 2.5.

Do I even need pytz? If not, how can I get around this error?

pylab requires pytz. The easiest way to install the package in Python is to run pip install pytz .

Today Python comes with a pre-installed peak, but use these instructions if you need to install it: https://pip.pypa.io/en/latest/installing.html
