Cannot import pandas after update of conda (PyQt4.QtGui import error)

[Auerilas]

Recently updated conda, using conda update --all. I have conda forge, so I should be using the latest recipes. On attempting to import pandas:

Code Sample, a copy-pastable example if possible

ImportError: No module named 'PyQt4.QtGui'

I can run this following:

In [14]: import PyQt5
In [15]: import PyQt4
In [16]: import PyQt5.QtGui
In [17]: import PyQt4.QtGui

ImportError                               Traceback (most recent call last)

----> 1 import PyQt4.QtGui

ImportError: No module named 'PyQt4.QtGui'

Any thoughts on how to proceed from here?

See #16322 (and some linked issues).

This is fixed in master and we'll be release 0.20.2 before too long. In the meantime, it seems like removing the pyqt4 directory in your site-packages should fix the problem.
