ImportError: No module named mpl_toolkits with maptlotlib 1.3.0 and py2exe
提问by RuiDC
I can't figure out how to be able to package this via py2exe now:
我现在不知道如何通过 py2exe 打包：
I am running the command:
我正在运行命令：
python setup2.py py2exe
via python 2.7.5 and matplotlib 1.3.0 and py2exe 0.6.9 and 0.6.10dev
通过 python 2.7.5 和 matplotlib 1.3.0 和 py2exe 0.6.9 和 0.6.10dev
This worked with matplotlib 1.2.x
这适用于 matplotlib 1.2.x
I have read http://www.py2exe.org/index.cgi/ExeWithEggsand tried to implement the suggestions for handling the mpl_toolkits since it's having become a namespace package.
我已阅读http://www.py2exe.org/index.cgi/ExeWithEggs并尝试实施处理 mpl_toolkits 的建议，因为它已成为命名空间包。
I'm trying to get an answer here too: http://matplotlib.1069221.n5.nabble.com/1-3-0-and-py2exe-regression-td41723.html
我也想在这里得到答案：http: //matplotlib.1069221.n5.nabble.com/1-3-0-and-py2exe-regression-td41723.html
Adding an empty __init__.pyto mpl_toolkits makes it work, but this is only a workaround to the problem.
将空添加__init__.py到 mpl_toolkits 使其工作，但这只是解决问题的方法。
Can anyone suggest what I need to make py2exe work with mpl_toolkits.axes_grid1 in matplotlib 1.3.0 ?:
任何人都可以建议我需要什么才能使 py2exe 与 matplotlib 1.3.0 中的 mpl_toolkits.axes_grid1 一起工作？：
test_mpl.py is:
test_mpl.py 是：
from mpl_toolkits.axes_grid1 import make_axes_locatable, axes_size
if __name__ == '__main__':
print make_axes_locatable, axes_size
setup2.py is:
setup2.py 是：
import py2exe
import distutils.sysconfig
from distutils.core import setup
# attempts to get it to work
import modulefinder
import matplotlib
import mpl_toolkits.axes_grid1
__import__('pkg_resources').declare_namespace("mpl_toolkits")
__import__('pkg_resources').declare_namespace("mpl_toolkits.axes_grid1")
modulefinder.AddPackagePath("mpl_toolkits", matplotlib.__path__[0])
modulefinder.AddPackagePath("mpl_toolkits.axes_grid1", mpl_toolkits.axes_grid1.__path__[0])
# end of attempts to get it to work

Most folders in the site-packages directory in a Python installation are packages (they have an __init__.py file). If there is no __init__.py file, then the package is called a namespace package. cx_Freeze has an option to indicate that mpl_toolkits is a namespace package, so the subpackages can be found.
Python 安装中 site-packages 目录中的大多数文件夹都是包（它们有一个 __init__.py 文件）。如果没有 __init__.py 文件，则该包称为命名空间包。cx_Freeze 有一个选项表明 mpl_toolkits 是一个命名空间包，因此可以找到子包。

There is a quite simple workaround to this problem. Find the directory from which mpl_tools is imported and simply add an empty text file named __init__.pyin that directory. py2exe will now find and include this module without any special imports needed in the setup file.
这个问题有一个非常简单的解决方法。找到从中导入 mpl_tools 的目录，然后添加一个以__init__.py该目录命名的空文本文件。py2exe 现在将查找并包含此模块，而无需在安装文件中进行任何特殊导入。
You can find the mpl_tools directory by typing the following in a python console:
您可以通过在 python 控制台中键入以下内容来找到 mpl_tools 目录：
import importlib
importlib.import_module('mpl_toolkits').__path__
I found the solution here https://stackoverflow.com/a/11632115/2166823and it seems to apply to namespace packages in general.
我在这里找到了解决方案https://stackoverflow.com/a/11632115/2166823，它似乎适用于一般的命名空间包。
