I regularly update my installation of Anaconda Python by running the Anaconda Python console and typing:
conda update anaconda
at the C:\Anaconda> prompt.
When I tried to run the Spyder IDE today, it died with the message:
…./anaconda/lib/python2.7/site-packages/IPython/qt.py:13: ShimWarning: The `IPython.qt` package has been deprecated. You should import from qtconsole instead.
Apparently, according to the discussion here, the problem is a compatibility issue the new version 4.0 of iPython. The solution is to downgrade the iPython console to version 3.2.1:
Here is how you “downgrade” the iPython console to the needed version 3.2.1. At the Anaconda command prompt, enter
conda install ipython=3.2.1
Thus, with the install command of conda, you can control the version by using the “=” suffix as above.
This solved the problem for me! (Wasted quite a lot of my time, however.)
I imagine that this problem will be corrected fairly quickly. By the way, I am using Python 2.7. I don’t know if the problem also occurs in Python 3.
