Hi there,

I was trying to use ipython notebook . I installed all the dependency libraries. However, I cannot use either the "--pylab=inline" option when launching ipython or "savefig" function in the Ipython console. When I tried to do either of them, an error message was returned "RuntimeError: Could not create write struct" resulting from execution of matplotlib. Also, a warning from the notebookApp prompt said "libpng warning: Application built with libpng-1.2.41 but running with 1.5.13".

However, I installed the newest libpng, uninstalled matplotlib with pip uninstall and reinstalled matplotlib with pip install (and during the build process, I can see that libpng1.5.13 is used for the building of matplotlib).

The configuration for my system is Mac OS X10.6, python2.7. Anybody has similar experience or some suggestiongs?

Thanks,

Jie

Hi Jie -- just to be clear -- are you trying to run IPython notebook on PythonAnywhere? It doesn't work here yet, there's some work we need to do first.
