This is how I know that rc_examples.download is set to True in get_sample_data(). It turns out the debugging messages I made reference to in my last message were being output and I just missed them in the noise. Right after matplotlib is initialized with matplotlib.rc_params() it seems that rcParams['examples.download'] is set to False as expected. By the time execution makes it to get_sample_data(), however, this value has somehow been set to True. To try identifying where this happens I have tried putting some debug output in RcParams.__setitem__(). Unfortunately this doesn't show anyone setting examples.download after the initial loading of matplotlibrc. Any ideas how/where this might get overridden? - Ben
