[PYTHON] Until you install Anaconda for data analysis on your Mac and launch the IDE

environment

Mac OSX: 10.11.3 Python: 2.7.10(System) Pyenv: 20160202 Anaconda: 3-2.4.1 * Latest version as of March 27, 2016 Python: 3.5.1(Anaconda)

Install Pyenv

brew install pyenv

• The brew command requires Homebrew to be installed.

Pyenv settings

Add the following.

~/.bash_profile

export PATH="$HOME/.pyenv/shims:$PATH"

Install Anaconda

Check the Anaconda version that can be installed with the following command

pyenv install --list | grep anaconda

Then install the specified version with the following command

pyenv install anaconda3-2.4.1

• Python when using Anaconda depends on the version of Python in Anaconda
• The standard Python version of Mac OSX 10.11 is 2.7.10, but Anaconda 3-2.4.1 is 3.5.1.

Package installation

To install the package, use pip in Anaconda. Note that if you execute the pip command without specifying Anaconda's pip, you will not be able to use it because Python, which is used as standard, will be called and installed (unverified).

~/.pyenv/versions/anaconda3-2.4.1/bin/pip install [package name]

e.g.

~/.pyenv/versions/anaconda3-2.4.1/bin/pip install pulp
~/.pyenv/versions/anaconda3-2.4.1/bin/pip install ortoolpy

Launch the IDE

Anaconda launcher screen launch

When you install Anaconda, a shortcut will be created on your desktop, so double-clicking it will bring up the Anaconda launcher screen.

• Of course, double-clicking the following .app will also start it.

~/.pyenv/versions/anaconda3-2.4.1/Launcher.app

Start Spyder (IDE)

You can launch Spyder (IDE) by clicking "Launch" to the right of spyder on the Anaconda launcher screen.

Summary

I am very grateful that the environment for data analysis can be constructed so easily. In the future, I would like to use it for data collection, processing, analysis, optimization, etc. I would like to post those articles as well.
