Anacondaをインストールする
とりあえず、Cygwin上でPython3を使えるようにして、さて、numpyだ、scipyだ、matplotだと思っていたんだけれど、同僚から「環境を統一しよう」と至極もっともな提案があり、彼がインストールしていたAnacondaをインストールすることになった。
というワケで、chocolateyでanaconda3をインストールした。
自宅でも学習できるように、自宅MacにもAnacondaをインストールすることにしよう。
brew を使えば簡単
Windows環境でchocolateyを使ったように、MacではHomeBrewのお世話になる。
% brew search anaconda Caskroom/cask/anaconda Caskroom/versions/anaconda2 % brew cask install anaconda ==> Migrating cached files to /Users/toshi/Library/Caches/Homebrew/Cask... ==> Caveats To use anaconda, you may need to add the ~/anaconda3/bin directory to your PATH environment variable, eg (for bash shell): export PATH=~/anaconda3/bin:"$PATH" ==> Satisfying dependencies complete ==> Downloading https://repo.continuum.io/archive/Anaconda3-4.1.1-MacOSX-x86_64.sh
というワケで、export PATH=~/anaconda3/bin:$PATH を.zshrcに書いて、source ~/.zshrc しておく。
pyenv ? virtualenv ?
とりあえず、仮想環境を作る必要性って感じないんだよな。コレ、要るかな？要らないよね？ってことにする。
OpenCVのインストール
OpenCVをひとまず使えるようにする。pipを使うのかとおもいきや、condaを使うのな。

よく分からないけれど、どこかのWebサイトで見たmenpo/opencv3をインストールすることにしよう。

ところで、こういうのって、qiita.comとかに書いとくと良いんだろうか。
