Ipython3筆記本不運行帶有MacPorts的

Question

安裝後，我安裝的IPython和IPython的筆記本的Python3.4版本

sudo port install py34-ipython 
sudo port install py34-notebook 

目前我使用Python 3.4.3作爲我的版本Python3的。

如果我使用ipython3 notebook，則會彈出Web瀏覽器。但是，如果我嘗試打開一個新的筆記本電腦，內核會立即關閉。

文件/Users/MYNAME/thread.py是Python 2語法。 更改爲其他目錄或刪除此文件或更改此文件的名稱。然後再次啓動筆記本服務器。名稱thread.py對Python 2中標準庫模塊的名稱有影響.IPython與Python 2和3一起使用相同的源代碼運行並導入錯誤的文件。
