Comment (by giovannibajo):
Wow, I'm actually impressed that people prefer to write something like 300
lines of code (numpy._importtools.py) just to save a dozen of import
statements... and of course break packaging of Python programs :)
AFAICT, {{{scipy/__init__.py}}} relies on numpy._importtools to import all
sub-packages into its namespace. We have two problems here to solve:
1. We need to make sure that all subpackges are bundled by !PyInstaller.
It cannot detect it by itself, because it doesn't see a raw import
statement. So it should be sufficient to add something like:
{{{
hiddenimports = ['scipy.misc', 'scipy.ffpack', 'scipy.lib', ...]
}}}
If we want to be very fancy, we could glob the filesystem and find out
all subdirectories instead of hard-coding a list (given that scipy itself
searches on the filesystem, it would strictly be correct).
To verify that this step has been succesful, it is sufficient to run
!ArchiveViewer.py onto the generated executable and look if all the
modules have been packaged.
1. At runtime, we need to fix the namespaces. This can be done through a
runtime hook (which is a file which is executed BEFORE the application
starts; look at rthooks.dat). There are couple of ways:
1. Something exactly like your suggested workaround. The import hook
can simply import the subpackages one by one and do a for loop to copy all
the symbols into the scipy namespace.
1. Monkey-patch numpy._importtools.py so that, instead of searching
within the disk, searches within the packaged archive (I am not sure how
exactly, though...)
1. Re-run scipy.pkgload() by passing it an explicit list of
subpackages; given its documentation, it should work. It should be
sufficient something like:
{{{
import scipy
scipy.pkgload("misc", "ffpack", "lib", ..) # same list of the import hook
}}}
I won't have time to face this in the next weeks (until the end of
August), so if you want to try for yourself go ahead and let me know.
