ここの指示に従って最近 ipython をインストールしました: http://ardiyu07.blogspot.com/2012/04/ipython-012-installation-in-cygwin.html。
実行する'ipython --pylab'
と、以下のエラーメッセージが表示されます。私はグーグルで検索し、このエラーに関する投稿を見つけましたが、コンテキストは異なります。--pylab 引数を指定して ipython を起動すると、私のエラーが発生します。これはmatplotlib guiの相互作用と関係があることは知っていますが、正確にはわかりません。ご指導ありがとうございます。
