Install Python On Macbook Pro

/ Comments off

The Python packaging for Spark is not intended to replace all of the other use cases. This Python packaged version of Spark is suitable for interacting with an existing cluster (be it Spark standalone, YARN, or Mesos) - but does not contain the tools required to setup your own standalone Spark cluster. This is my preferred way to install Python and Jupyter notebook for doing scientific data analysis. There are many alternative ways of doing this that you can find on Google. I’m doing this on a MacBook Pro (Retina, 13-inch, Early 2015) with macOS High Sierra 10.13.3. The reason I did this was because of work. I could choose a Macbook Pro again, but with the current Windows laptops on the market, you’ll get a lot more bang for your buck. Install Python in.

Mac OS X comes with Python 2.7 out of the box.

You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.

The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

Doing it Right¶

Let’s install a real version of Python.

Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.

Note

If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note

If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.

While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run

The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file

If you have OS X 10.12 (Sierra) or older use this line instead

Now, we can install Python 3:

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

will launch the Homebrew-installed Python 2 interpreter (if any).

will launch the Homebrew-installed Python 3 interpreter.

If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.

The rest of the guide will assume that python references Python 3.

Pipenv & Virtual Environments¶

The next step is to install Pipenv, so you can install dependencies and manage virtual environments.

A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.

For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.

So, onward! To the Pipenv & Virtual Environments docs!

In the past, I used virtualenv to manage virtual environments with Python 2. Python3 has built-in handling of virtual environments, so I use that here instead. If you need to use Python 2, then you’ll want to install virtualenv (see first link at the bottom).

Install

Install Homebrew

All of these steps are done in the Mac OS Terminal, so start that first.

First install XCode:

Install Python On Macbook Pro

Install Homebrew:

Open or create the file ~/.bash_profile and write:

Install Python 3

As of 2018-4-9, this will install Python 3 (I think previously it installed Python 2):

Set up virtual environment

By default, Python 3 comes with the ability to create virtual environments.

Make a folder to host your virtual envs:

Create a virtual env for Jupyter:

Run virtual environment and Jupyter

Mac

Start the virtual env:

Macbook

Install packages for scientific computing:

Run Jupyter:

A browser window will open with the Jupyter file browser in your current working directory.

Exit Jupyter and virtual environment

Jupyter notebook will run in your terminal window until you close it (with Ctrl-C).

You can close the virtual environment with:

UPDATE 2018-04-19: A very useful (and IMO essential) addition to Jupyter notebook is the Table of Contents extension. I show how I install this in a different blog post.
