traitsui editorをインポートするとPythonでwxエラーが発生する

Question

私の質問は同じto this unanswered questionですが、私は自分のコンテキスト（パッケージバージョン）を追加したいと思っていました。 （私はSE規則に従ってこれをしなければならない方法を私に教えてください）。

次の行：

import wx 
from traitsui.api import View, Item, Group, HSplit, Handler, EnumEditor, FileEditor 

原因次のエラー：

私はここに、更新されたパッケージ間の非互換性を疑うバージョンです：

Python 2.7.12 on Ubuntu 16.04 

traits==4.6.0 
traitsui==5.1.0 
wxPython==4.0.0b2 
wxPython-common==3.0.2.0 

と私はセット（端末では、Pythonに入る前に）：

export ETS_TOOLKIT=wx 

Answer 1

問題は、静的メソッドの "_"バージョンの削除であり、traitsuiはまだ完全に移行されていません。 https://docs.wxpython.org/MigrationGuide.html#static-methodsを参照してください。
