install scikit-learn for python 3.3 on windows 7 - scikit-learn

Question

I am really new to the use of Python and the associated packages that can be installed.
As a biologist I am looking for a lot of new packages that would help me model species systems, ecological change etc.. and after a lot of "Google-ing" I came across scikit-learn.
However, I am having trouble installing it. And I will take this moment now to apologise for the length of this post.
I am using 64bit Python 3.3 and have the associated NumPy (MKL 1.7.0) and SciPy. I installed distribute which worked fine and allows me to use easy_install.
So to install scikit-learn, I tried using the cmd prompt (Windows) run in administrator mode, and then also through Python command line.
I placed the downloaded and extracted tar.gz file in the Lib\site-packages folder.
When I run the command
easy_install scikit-learn
in cmd prompt.
Then this is the following output:
C:\Python33\Lib\site-packages>easy_install -U scikit-learn

^
SyntaxError: invalid syntax
C:\Python33\Lib\site-packages>
So the little ^ seems to be pointing at the " after RNGS with %r. Which from what I can tell is in the 'init' file from the sklearn folder found in the .tar.gz file.
I also get the same result when running it in the Python GUI and command line.
How can I install scikit-learn with Python 3.3? Is there some way of building it or editing the file to get past this invalid syntax error?
Any help would be greatly appreciated. And I am very sorry for it being such a long post. I was just trying to get all the details in there.
Thanks
Simon

Answer 1

scikit-learn does not support Python 3 yet. For now you need Python 2.7.
Proper support for Python 3 is expected for the 0.14 release scheduled for Q2-2013.

Answer 2

I am no expert, but in my understanding the print statement in Python 3.* is now a function, called like: print(). So, a quick solution in this case is to change
print "I: Seeding RNGs with %r" % _random_seed
to
print("I: Seeding RNGs with %r" % _random_seed)
