インポートmatplotlib.pyplotがハングする

私はmatplotlibをOS X 10.8.4上で稼働させようとしています。 matplotlibと依存関係（libping、freetype、numpy、scipy）をインストールしました。私はmatplotlibをうまくインポートすることができます。しかし、matplotlib.pyplotをインポートしようとすると、ハングします。エラーはなく、何も起こらないだけです。

_>>> import matplotlib.pyplot
_

...私は多分何も起こらない20分待っていました。私はバージョン1.2.1を使用していますが、それをアンインストールしてバージョン1.2.0を試しましたが、役に立ちませんでした。 SO matplotlib.pyplotでのインポートエラーに関する多くの質問を見てきましたが、ハングするところは何もありませんでした。次に、Enthought/Canopy pythonディストリビューションですが、繰り返しになりますが、同じ問題が発生しています。インポートを強制終了すると、次のようになります。

更新

_import matplotlib.pyplot_を数時間実行してからインポートを中断すると、次の出力が得られます。

誰かが再帰的なfor x in walk(new_path, topdown, onerror, followlinks):が何を示しているか知っていますか？

Mac OS X MavericksおよびYosemiteでの問題は、次の手順で修正できます。

cd ~/.matplotlib/
fc-list  # Should take a couple minutes.

fc-listの実行が完了すると、import matplotlib.pyplot as pltを使用してパッケージをインポートできるようになります。 github issue がソリューションです。バグはフォントキャッシュに関連しているようです。

私は何が起こっているのかを理解しました。うまくいけば、ソリューションが他の人に役立つでしょう。の中に /usr/X11/libフォルダ自分自身を指すディレクトリへのシンボリックリンクがありました。これにより、無限ループが発生したようです。リンクを削除すると、インポートが機能しました。

Linuxでも同じ問題が発生していました。

Matplotlibには、使用するGUIバックエンドを理解する上でいくつかの問題があったことが判明しました。

Tkinterバックグラウンドを使用することを明示的に言って-デフォルトでは、次のコマンドを使用して問題を解決しました。

%matplotlib tk

これに続いてインポート

import matplotlib.pyplot as plt

期待どおりに動作しました。
