[pyqtgraph] when install pyqt4, an error happen for "from pyqtgraph.Qt import QtWidgets"

[Deckard Zhang]

when only install pyqtgraph, it is ok to run "from pyqtgraph.Qt import
QtWidgets"
however, when I install pyqt4 together, an error happen when run
"from pyqtgraph.Qt import QtWidgets"

ImportError: cannot import name QtWidgets


What's wrong? Thank you

QtWidgets was introduced in Qt5. See :
http://pyqt.sourceforge.net/Docs/PyQt5/pyqt4_differences.html#qtgui-module

If you are using PyQt4, you should import QtGui instead of QtWidgets
