iPython/jupyter qtconsole fails to start in anaconda 2.4.0
Question: After upgrading Anaconda3 (32-bit) from version 2.3.0 to 2.4.0 (by
reinstalling Anaconda) on my Windows 7 64-bit machine, the iPython/jupyter
qtconsole fails to start: when executing `jupyter-qtconsole.exe` or `jupyter-
qtconsole-script.py`, the following error appears:

    
    
    Traceback (most recent call last):
      File "C:\Anaconda3\Scripts\jupyter-qtconsole-script.py", line 1, in <module>
        from qtconsole.qtconsoleapp import main
      File "C:\Anaconda3\lib\site-packages\qtconsole\qtconsoleapp.py", line 45, in <module>
        from qtconsole.qt import QtCore, QtGui
      File "C:\Anaconda3\lib\site-packages\qtconsole\qt.py", line 23, in <module>
        QtCore, QtGui, QtSvg, QT_API = load_qt(api_opts)
      File "C:\Anaconda3\lib\site-packages\qtconsole\qt_loaders.py", line 285, in load_qt
        result = loaders[api]()
      File "C:\Anaconda3\lib\site-packages\qtconsole\qt_loaders.py", line 192, in import_pyqt4
        from PyQt4 import QtGui, QtCore, QtSvg
    ImportError: DLL load failed: The specified procedure could not be found.
    

The qtconsole still works in an Anaconda 2.3.0 environment I created. After
comparing the `.\Lib\site-packages\PyQt4` directories of both the 2.3.0 and
2.4.0 environments, I noticed that the latter is missing all the Qt dll's and
Qt directories. After a quick search, I discovered the Qt dll's are now
located in `C:\Anaconda3\Library\bin`. This directory is also set in the
system PATH environment variable, but the problem is still there. How to solve
this issue?


Answer: After copying QtCore4.dll and QtGui4.dll from `C:\Anaconda3\Library\bin` to
`.\Lib\site-packages\PyQt4`, as suggested
[here](http://stackoverflow.com/a/5869748/1504026 "here"), I got the qtconsole
going again. However, this is not a very elegant solution.
