[Numpy-discussion] Yes, this one again "ImportError: No module named multiarray"

Glad you got it working!  For those who might be interested, the
distinction between the example I linked to and packaging tools like
PyInstaller or py2exe, is that
NumpyBuiltinExample<https://github.com/patmarion/NumpyBuiltinExample>uses
static linking to embed numpy as a builtin module.  At runtime, there
is no dynamic loading, and there is no filesystem access.  The technique is
targeted at HPC or embedded systems where you might want to avoid touching
the filesystem, or avoid dynamic loading.
