Your application is incorrect. You have to import PyQt4 like so:
from PyQt4 import QtCore, QtGui
Thanks, that fixes the problem. But it seems like a stretch to call the
program "incorrect" when it works just fine. Why does PyInstaller
understand one form of import but not the other?
Also, there is no need to import sip.
True. In my real program I'm importing sip to do this:
import sip
sip.setapi('QString', 2)
sip.setapi('QVariant', 2)
from PyQt4.QtCore import *
from PyQt4.QtGui import *
Which leads me to another problem. When I package the larger program
with PyInstaller and run the EXE, I get this error:
ValueError: API 'QString' has already been set to version 1
It seems as though PyQt is somehow getting loaded before my sip.setapi
calls, even though I haven't explicitly imported it yet. Again, it works
correctly when I run the .py file directly. Is there a workaround for this?
