This is the import used for the `gui=qt` or `matplotlib=qt` initialization. Import Priority: if Qt has been imported anywhere else: use that if matplotlib has been imported and doesn't support v2 (<= 1.0.1): use PyQt4 @v1 Next, ask QT_API env variable if QT_API not set: ask matplotlib via rcParams['backend.qt4'] if it said PyQt: use PyQt4 @v1 elif it said PySide: use PySide else: (matplotlib said nothing) # this is the default path - nobody told us anything try: PyQt @v1 except: fallback on PySide else: use what QT_API says iÿÿÿÿN(t check_version(tload_qtt loaded_apit QT_API_PYSIDEt QT_API_PYQTt QT_API_PYQT5t QT_API_PYQTv1tQT_API_PYQT_DEFAULTcCs{|dkrdS|jjddƒ}|dkr5dS|jƒdkrNtgS|jƒdkrgtgStd|ƒ‚dS(Ns backend.qt4tpysidetpyqt4s3unhandled value for backend.qt4 from matplotlib: %r(tNonetrcParamstgettlowerRRt ImportError(tmpltmpqt((sV/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/external/qt_for_kernel.pytmatplotlib_options4s  cCsÇtƒ}|dk r|gStjjddƒ}|dk rWt|jdƒ rWtgStj jddƒ}|dkrŽt |ƒptt gS|t kr¼t d|djt ƒfƒ‚n|gSdS(sOReturn a list of acceptable QT APIs, in decreasing order of preference t matplotlibs1.0.2tQT_APIs'Invalid Qt API %r, valid values are: %rs, N(RR tsystmodulesR Rt __version__RtostenvironRRt_qt_apist RuntimeErrortjoin(tloadedRtqt_api((sV/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/external/qt_for_kernel.pyt get_optionsAs    (t__doc__RRtIPython.utils.versionRtIPython.external.qt_loadersRRRRRRRRRRtapi_optstQtCoretQtGuitQtSvgR(((sV/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/external/qt_for_kernel.pyts  4
