Hi Adam,

The NYU SVS tiling script doesn't use OpenSlide Python: it uses pyOpenSlide,
which is an older, unmaintained Python binding.  The script has other
problems as well; for example, it tries to read the entire slide into
memory, which doesn't generally work on 32-bit systems.

I'd suggest using VIPS instead.  It can read a slide file using OpenSlide
and generate a Google Maps pyramid:
