Getting Going with Python on Mac OS X The aim of this web page is to help you get started with Python on Mac OS X. We will explain what a package management tool is, how to download conda package management tool via the Anaconda installer, and guide you on the OS X Terminal application so that you can use conda from the command line. Finally, we will wrap up by installing one library with conda.

To run in the future, simply open VirtualBox, select your operating system e.g. Riak download ubuntu for mac download. To change back to Mac OS X, press the host key once (as indicated at the bottom right of the Linux window) If you get a black screen on the Linux window, simply double click to restore session. Note: to close VirtualBox, in the open Ubuntu window, select your name on the menubar and select shutdown; when it says Aborted or Powered Off under your Ubuntu Linux boot in the VirtualBox program, it is safe to close VirtualBox. Unfortunately, if a complete fail occurs, you will need to restart the installation process. Ubuntu Linux and select Start or ] If the installation fails for some reason or another, select the operating system name, while in VirtualBox, and then select Discard.

What Is a Package Management Tool? A package management tool is a software application that helps you manage software libraries that enable you to get your work done. These software libraries may relate to plotting for scientific publication or accessing certain kinds of data, for example.

When you start using Python, you will want use software libraries that are not part of the standard Python installation. For example, you may wish to use the for meteorological data and visualization. Anaconda from Continuum Analytics will help you install metpy easily.

Installing the conda Package Management Tool The conda package management tool is part of the Anaconda software package. Install conda by navigating to the. Scroll down to the “Anaconda for OS X” portion of the web page. Download the Python 3.5 version by clicking on the “Mac OS X 64 bit Graphical Installer” link. It is a big download, so it is best to be on fast network. Open the installer file you just downloaded. It should be named something like Anacondaversion-MacOSX-x8664.pkg.

This action will guide you through the. The second “Read Me” step is important, as the installation will make some modifications that the OS X Terminal application can make use of. We cover the OS X Terminal next.

OS X Terminal Application The OS X Terminal is a software program that gives you the ability to give text based instructions to your computer. As you make progress in geoscientific programming, you will probably use the Terminal a lot, so it will benefit you to become familiar with it. For this exercise we will open up the Terminal by going to the OS X Finder and navigating to the Application, Utilities folder.

There you will find the Terminal application which you can double click on to launch. In the Terminal application, you will see a character such as $ symbol known as the command line. The command line is where you give text instructions to your computer.

Interacting with conda Let’s make sure conda is installed by entering this instruction on the command line. # packages in environment at /Users/chastang/anaconda: # alabaster 0.7.7 py350 anaconda 4.0.0 np110py350 anaconda-client 1.4.0 py350. Numexpr 2.5 np110py350 numpy 1.10.4 py350 odo 0.4.2 py350.

Yaml 0.1.6 0 zeromq 4.1.3 0 zlib 1.2.8 0 which will list linked packages in a conda environment. You’ll notice libraries such as the scientific computing library that you will probably be making use of. If You Have Problems with conda list If conda list worked without trouble, skip this subsection.

If that last conda list command gave you an error, it is possible that you are running the wrong flavor of the OS X Terminal (or more precisely the wrong Unix shell). Ensure you are running the bash shell by going to Terminal, Preferences menu, and verifying that /bin/bash is selected. If you change it, please quit, and restart the Terminal application. Getting Our Feet Wet by Installing Metpy with conda We first have to give conda an instruction on where to find metpy on the conda-forge channel.
