In preparation for Hilary Mason‘s workshop on Machine Learning at Strange Loop 2011 I was notified “it would be great if you could bring a machine that has python 2.5+ installed with numpy/scipy, nltk, and git”. Although Snow Leopard comes preinstalled with Python, the version was not sufficient for NumPy so I went through the following steps to get my machine prepared. (Note: As far as I know the Git version that comes preinstalled with Mac OS X 10.6.8 should be fine.) I thought others might find this useful.
1) Install the GNU Fortran compiler 4.2.3
(http://r.research.att.com/tools/)
http://r.research.att.com/gfortran-4.2.3.dmg
2) Install Python 2.7.2
(http://www.python.org/getit/)
http://www.python.org/ftp/python/2.7.2/python-2.7.2-macosx10.6.dmg
If everything goes correctly you should see the IDLE app under the Applications/Python 2.7 folder and be able to launch without issue.
3) Install NumPy 1.6.1
(http://numpy.scipy.org/)
http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-py2.7-python.org-macosx10.6.dmg/download
4) Install SciPy 0.9.0
(http://www.scipy.org/)
http://sourceforge.net/projects/scipy/files/scipy/0.9.0/scipy-0.9.0-py2.7-python.org-macosx10.6.dmg/download
5) Install LibYAML 0.1.4
(http://pyyaml.org/wiki/LibYAML)
http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz
After uncompressing into a folder, to build and install, run:
$./configure
$make
$sudo make install
6) Install PyYAML 3.10
(http://pyyaml.org/wiki/PyYAML)
http://pyyaml.org/download/pyyaml/PyYAML-3.10.tar.gz
After uncompressing into a folder, run:
sudo python setup.py install
7) Install NLTK 2.0.1
(http://www.nltk.org/)
http://nltk.googlecode.com/files/nltk-2.0.1rc1.dmg
The normal install process didn’t seem to work for me. So after attempting that, I ran the following to install NLTK:
cd /tmp/nltk-installer
sudo python setup.py install.
