python matplotlib ipython

matplotlib散点在ipython笔记本中工作，但在控制台中不工作,python,matplotlib,ipython,ipython-notebook,Python,Matplotlib,Ipython,Ipython Notebook,我正在尝试学习使用matplotlib，并按照教程绘制散点图，在散点图中指定点的大小。（）我使用命令ipython--pylab在Mac OS X上运行ipython，并得到以下错误 AttributeError Traceback (most recent call last) /Library/Python/2.7/site-packages/matplotlib-1.4.x-py2.7-macosx-10.8-intel.egg/m

我正在尝试学习使用matplotlib，并按照教程绘制散点图，在散点图中指定点的大小。（）

我使用命令

ipython--pylab

在Mac OS X上运行ipython，并得到以下错误

AttributeError: 'numpy.ndarray' object has no attribute 'get_matrix'

但是，如果我在一个ipython笔记本中运行相同的代码，该笔记本使用命令

ipython notebook--pylab=inline

启动，它工作正常

如何从控制台执行此操作

其他信息：

我在控制台和ipython上运行相同版本的numpy 笔记本：numpy.版本='1.9.0.dev-7457f15'
操作系统是OSX 10.8.5
如果我使用
```
ipython
```
而不是
```
ipython--pylab
```
运行，我会得到相同的结果错误
Python 2.7.5（默认值，2013年10月13日，13:05:22）
IPython 2.0.0-dev

谢谢

看起来这是

matplotlib

端的

后端问题。查看错误消息的最后一部分。它表示macosx
后端
中存在不正确的情况，该后端用作OSX
环境中的交互式后端
它在内联模式下工作的原因：pylab=inline
证实了这一点。与内联模式一样，不是交互式后端，而是一个非交互式后端（最有可能是inline
backend）。所以，它起作用了
解决方案可能是@Matt建议的，切换到稳定版本的matplotlib
检查两个解释器中的numpy（numpy.\uuu version\uuu
）版本是否相同。请提供您通常使用的所有软件的验证。OSX（和Maverick甚至更多）使用Python做一些奇怪的事情，尤其是numpy。也可以尝试使用稳定的Matplotlib。添加你的OSX版本（10.8版Montain Lion），即使在这里你可以从追踪中猜到它，也不是每个人都愿意去搜索。最后，我们试图说服人们不要使用——pylab
，它有不良的副作用。在IPython 1.0及更高版本上，如有必要，最好使用显式导入和%matplotlib inline
。谢谢Matt。我尝试使用ipython
而不是ipython--pylab
，但得到了相同的错误。我还尝试使用了python
，同样出现了相同的错误。（详细信息，但对于开发版本，您可能希望给出确切的提交import-IPython:print-IPython.sys\u-info（）
。您也在numpy dev上，请尝试numpy stable。然后我们可能还可以测试--pylab=qt
或gtk
来确认这一点。感谢您的解释和帮助，@Matt&@CT Zhu！我不知道我的版本不稳定。在使用pip install numpy重新安装后--升级pip install scipy--升级sudo pip install matplotlib--升级sudo-pip-install-ipython--升级sudo-pip-install-pandas--升级sudo-pip-install-sympy--升级sudo-pip-install-nose--升级一切都很好
