为什么 python 在 numpy.core.ma 上卡住了？
我正在尝试在我的 mac 10.6.7 32 位机器上设置 pylab；使用 virutalenv 将我正在做的事情与其他事情隔离开来（来自 ruby/rvm 背景，这只会让我感觉更好 - 但如果它不是“python 方式”，我愿意接受纠正）。
我安装了以下模块/库：
DateUtils-0.5.1-py2.7.egg-info numpy-1.5.1-py2.7.egg-info
IPython pip-0.8.3-py2.7.egg
configobj.py pylab.py
configobj.pyc pylab.pyc
dateutil pymc
dateutils pymc-2.1beta-py2.7.egg-info
easy-install.pth python_dateutil-2.0-py2.7.egg-info
enthought pytz
ipython-0.10.1-py2.7.egg-info pytz-2011e-py2.7.egg-info
matplotlib scipy
matplotlib-0.91.1-py2.7.egg-info scipy-0.9.0-py2.7.egg-info
nose setuptools-0.6c11-py2.7.egg
nose-1.0.0-py2.7.egg-info setuptools-0.6c12dev_r88795-py2.7.egg
numpy setuptools.pth
我唯一无法解释的是考虑；我从未安装过他们的 python 解决方案 - 必须是其他东西的依赖项。
Numpy 似乎工作得很好，matplotlib 可以毫无问题地导入；两者都来自外壳。当我调用普通的 ipython 时也没有问题。但是当我尝试使用 pylab 时，我的 python 在 numpy.core.ma 上卡住了，如下所示：
File "/Users/davidbgonzalez/.virtualenvs/VirtPy27/lib/python2.7/site-packages/matplotlib/numerix/ma/__init__.py", line 16, in <module>
from numpy.core.ma import *
ImportError: No module named ma
回到这里，我打开了 __init__.py 和一个提示，如 此处。果然，ma是在numpy.ma中找到的，而不是numpy.core.ma；通过 import numpy.ma 进行验证。
我更改了有问题的行：
from numpy.core.ma import * -> from numpy.ma import *
并得到一个新的、非常相似的错误：
File "/Users/davidbgonzalez/.virtualenvs/VirtPy27/lib/python2.7/site-packages/matplotlib/numerix/npyma/__init__.py", line 7, in <module>
from numpy.core.ma import *
ImportError: No module named ma
但是当我将 numpy.core.ma 的实例更改为 numpy.ma 时，我得到了一个可怕的结果：
Bus error
我愿意接受任何解决方案。
I'm trying to set up pylab on my mac 10.6.7 32 bit machine; using virutalenv to isolate what I'm doing from everything else (coming from a ruby/rvm background this just makes me feel better--but I'm open to correction if it's not the "python way").
I have the following modules/libs installed:
DateUtils-0.5.1-py2.7.egg-info numpy-1.5.1-py2.7.egg-info
IPython pip-0.8.3-py2.7.egg
configobj.py pylab.py
configobj.pyc pylab.pyc
dateutil pymc
dateutils pymc-2.1beta-py2.7.egg-info
easy-install.pth python_dateutil-2.0-py2.7.egg-info
enthought pytz
ipython-0.10.1-py2.7.egg-info pytz-2011e-py2.7.egg-info
matplotlib scipy
matplotlib-0.91.1-py2.7.egg-info scipy-0.9.0-py2.7.egg-info
nose setuptools-0.6c11-py2.7.egg
nose-1.0.0-py2.7.egg-info setuptools-0.6c12dev_r88795-py2.7.egg
numpy setuptools.pth
The only one I can't account for is enthought; I have never installed their python solution -must be a dependency of something else.
Numpy appears to be working just fine, matplotlib can be imported without issue; both from a shell. When I call just plain ipython no trouble either. But when I try and use pylab I python chokes on numpy.core.ma as in:
File "/Users/davidbgonzalez/.virtualenvs/VirtPy27/lib/python2.7/site-packages/matplotlib/numerix/ma/__init__.py", line 16, in <module>
from numpy.core.ma import *
ImportError: No module named ma
Backing into this I opened the __init__.py and a prompt as alluded to here. Sure enough, ma is found in numpy.ma not numpy.core.ma; verified via import numpy.ma.
I change the offending line:
from numpy.core.ma import * -> from numpy.ma import *
And get a new, very similar, error:
File "/Users/davidbgonzalez/.virtualenvs/VirtPy27/lib/python2.7/site-packages/matplotlib/numerix/npyma/__init__.py", line 7, in <module>
from numpy.core.ma import *
ImportError: No module named ma
But when I change that instance of numpy.core.ma to numpy.ma I get a dreadful:
Bus error
I'm open to any solutions.
