IPython 0.11 has just been released. It's amazing how many new features are now available in this Python “comprehensive environment for interactive and exploratory computing”.
The installation of IPython is simple if you use
easy_install. However, to benefit from the new
qtconsole, you'll need to have a working Qt framework and install either PyQt4 or PySide, as documented here. Only the latter worked for me, at the moment. Of course, we also need to install the Qt SDK. This is quite straightforward as OS X packages are available from Nokia download page. Be aware that the compilation is rather long (about 30’ on my Macbook air 2010).
Here is how I did for the Python part:
$ sudo easy_install readline $ sudo easy_install ipython $ sudo easy_install pyzmq
Instead of building
PySide myself, I downloaded a package from here (
pyside-1.0.5-qt47-py27apple.pkg). We need to tell OS X where to find the Qt framework. I added the following line in my
Note that it is
DYLD_FRAMEWORK_PATH, and not
Then, we can test that everything is working by trying
$ ipython qtconsole --pylab=inline
No need to tell a long story because everything has been nicely summarized on Chris Fonnesbeck's nice post: Innovations in iPython. However, just for the record, here are some of the new features:
%run magiccommand that allows to run any python script and load all of its data directly into the interactive namespace. Take a look at the example provided by Chris Fonnesbeck: He is actually loading a Python script saved as a gist on Github.
$ python configure.py -d /Library/Python/2.7/site-packages/ $ make $ sudo make install
And for PyQt:
$ python configure.py -k -d /Library/Python/2.7/site-packages/ $ make $ sudo make install
I got a lot of warnings saying that Lion was currently not supported during the compilation.
