This has to to with the default backend of matplotlib, which macOS doesn’t really like. Click Downloads, then download the latest version from there: This downloads the appropriate 64-bit version of the latest Python.

The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. If you installed python on mac and tried to use matplotlib to make beautiful plots for your papers, you might get into this error RuntimeError: Python is not installed as a framework.

Now, you only need to remember to install modules using this slightly different line: python -m pip install MODULENAME -userĭone! Enjoy python on your supercomputer. Note the –user flag, which is good if you can’t sudo (as it was for me on the Caltech supercomputer).

So, how to get pip and install modules anyway? The python people have a script precisely for this: wget Anaconda works on Windows, Mac, and Linux, provides over 1,500 Python packages, and is used by over 15 million people. This was because I was on a supercomputer which already had a python distribution installed and I didn’t want to deal with the scipy dependancies (e.g. This is only for experienced users who want to try incoming changes and help identify bugs before an official release.

The latest and greatest Django version is the one that’s in our Git repository (our revision-control system). I recently got across the situation that I did not want to use a virtual environment. Option 2: Get the latest development version. A virtual environment is a semi-isolated Python environment that allows packages to be installed for use by a particular application, rather than being installed system wide. You have created the box, but you’re still out of it. Starting with Python 3.4, it is included by default with the Python binary installers. The virtual environment is physically located in ~/box. Again, if you screw something up, you can just delete the box and start again. You can have different boxes for different projects, or a single box for all your python stuff. Python’s virtual environments are kind of separate boxes, where you can install modules and packages locally. The easiest way to safely install python on a MAC is homebrew. Homebrew installs a new version of python (by default the latest 2.x version available) and set is as default. I will also stay with python 2 for now, but see below for some info on python 3 (see also here for more). However, it is advisable to install a local distribution and do your scientific stuff from there… If you screw something up, you can just delete everything and your OS is safe. Most (if not all) unix systems already come with a python distribution installed. This is a step-by-step guide to the best way I found to install and use python for science, the easy (less hackable) way comes first, and the long way comes next. All sort of scientific algorithms are already there (written and debugged!), you just have to use them. Install XCode Install GCC using Apples Command Line Tools Get a Package Manager. Python is cool, especially if you a scientist.
