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
