This post describes how to install IPython on a Mac OS X, Mountain Lion. Step by step, it explains how to install Python, Homebrew, Virtualenv, IPython, IPython Notebook and some useful libraries like Matplotlib.
Installing the matplotlib. Before working with the matplotlib library, we need to install it in out Python environment. Let's see the following method of installing matplotlib library. Using Anaconda distribution of Python. The Anaconda distribution is an easiest way to install matplotlib library because matplotlib is pre-installed in it.

It can be difficult to install a Python machine learning environment on Mac OS X. Python itself must be installed first, and then there are many packages to install, and it can be confusing for beginners. In this tutorial, you will discover how to setup a Python 3 machine learning and deep learning development environment using macports. If you use your package manager (MacPorts, brew,) to later install additional programs that depend on Matplotlib, the package manager will install it regardless. If you install a Python package via pip, and pip installs it in your package manager tree (MacPorts, brew,), the package manager might complain. For example, MacPorts does not.
Matplotlib is a python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. Matplotlib can be used in Python scripts, the Python and IPython shell (ala MATLAB or Mathematica), web application servers, and six graphical user interface toolkits.

Mac OS X comes with Python 2.7 already installed, that can be used for learning but which might be out of date. Therefore, in this post we will explain how to install the real version of Python as well, which is better for developing.
Install XCode
Go to the Apple Store and download the free version of XCode.
Once installed, launch the application from the Launchpad menu.
In the upper menu go to Xcode –> preferences…, or alternatively use the shortcut cmd+,.
Once in the preferences window go to the Downloads tab and install the Command Line Tools, which is in the Components section. To install it you just need to click in the right arrow.
Install Homebrew
To download and install Homebrew you need to run the following command in the Terminal:
$ ruby -e “$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)”
Install Python 2.7
Now it’s very easy to install Python! just write the following in your Terminal:
$ brew install python
Unfortunately, when we run python on the Terminal, we will still be using the preinstalled Python that comes with Mac OS X. We need to change the path to point to the new version of Python.
Open (or create if you don’t have it yet) the file ~/.profile and write the following lines in it:
PATH=/usr/local/bin:/usr/local/share/python:$PATH
export PATH
The good thing about installing Python with Homebrew is that you also install pip and Distribute, which extend the packaging and installation facilities provided by the distutils in the standard library.
Virtual Environment
Aiptek input devices driver download for windows 10. A good practice is to use a virtual environment to have all the packages that you are using for one project in the same folder. It is more easy to share and maintain.
To install Virtualenv:
$ sudo pip install virtualenv
Let us create a new virtual enviroment, called envipython
$ virtualenv envipython
which will create the folder envipython. To activate this environment:
$ source envipython/bin/activate
Note that the command line has changed to somehting like (envipython)$.
From now on, we will install the packages using this virtual environment. If you don’t want to use a virtual environment, you can install them in your machine with the same command lines.
Install IPython and IPython Notebook
$ pip install ipython
IPython comes with a very nice web-based notebook environment, which allows you to run python scripts in a similar way as with Mathematica or Matlab.
To install it, you will need to add the following libraries:
$ brew install freetype
$ brew install libpng
$ pip install readline
$ pip install tornado
$ brew install zeromq –universal
$ pip install pyzmq
$ pip install pygments
$ brew install pyqt
$ pip install jinja2
And that’s it! To run your IPython Notebook you only need:
$ ipython notebook
If you also want to install MathJax, which is an open source JavaScript display engine for mathematics, you need to enter to the IPython shell and type the following:
$ ipython
In [1]: from IPython.external.mathjax import install_mathjax
In [2]: install_mathjax()
Optional Science Packages
$ pip install numpy
$ pip install scipy
For Matplotlib you also have to install the library pkg-config (which in my case, it was already installed). Moreover, you might want to install ffmpeg, which allows to save movies using matplotlib.animation library.
$ brew install pkg-config
$ brew install ffmpeg
$ pip install matplotlib
Install Matplotlib Mac Brew
Whohaaa!! that was a little bit of installation!?! Hope it also worked for you! 🙂
