cx_freeze can't find oslo module

Question

I'm trying to use cx_freeze to create a Windows executable from a Python script that imports pyrax (to interface with Rackspace). Pyrax requires oslo (https://github.com/openstack/oslo.utils), a module for working with OpenStack that I have installed. When I try to run the compiled .exe, it says that it can't find the module 'oslo.utils'. When I try to include that module, or just the oslo module, in my setup.py file, I get the following error:

running build
running build_exe
Traceback (most recent call last):

I'm on Windows 8 running Python 2.7 via a Continuum Anaconda install. I've installed oslo v1.0.0 using pip (and reinstalled it in an attempt to fix this, but to no avail). Cx_freeze is version 4.3.3, and the oslo module not an egg or zip, but is foldered with everything else under site-packages.

'Import oslo' and 'import oslo.utils' both work in the interpreter. Other modules manually included in setup.py work correctly. My setup.py file looks like this:

import sys
from cx_Freeze import setup, Executable


# GUI applications require a different base on Windows (the default is for a
# console application).
base = None
if sys.platform == "win32":
    base = "Win32GUI"

# include email.__init__ lazy imports manually for pyrax
MIMENAMES = [
    'audio',
    'base',
    'image',
    'message',
    'multipart',
    'nonmultipart',
    'text',
    ]

email_includes = ['email.mime.' + x for x in MIMENAMES]

includes = ['oslo.utils']
includes.extend(email_includes)

include_files = []

execu = Executable(
  script = "main.py",
  initScript = None,
  base = base,
  targetName = "main.exe",
  compress = False,
  copyDependentFiles = True,
  appendScriptToExe = False,
  appendScriptToLibrary = False,
  icon = None
)

setup(  name = "issgmain",
        version = "0.1",
        description = "my description",
        options = {"build_exe": {"includes":includes, "include_files": include_files}},
        executables = [execu]
        )

Thoughts and workarounds much appreciated. Thanks!

Reposting as an answer:

Add to the build_exe options:

"namespace_packages":["oslo"]

oslo is a namespace package, and cx_Freeze needs to know about it for things to work correctly.

Apparently you also need to add it to packages:

"packages":["oslo"]

I'm not sure why this step is needed as well.
