Question

我正在使用Mac Yosemite和Anaconda的Python 3.4发行版。每当我做的时候

 import matplotlib.pyplot as plt
 ...
 plt.semilogy(x, y)
 plt.show()

在挂断状态下弹出一个空窗口。

我看到了类似帖子：Matplotlib not showing up in Mac OSX，建议使用

sudo port install py25-matplotlib +cairo+gtk2
sudo port install py26-matplotlib +cairo+gtk2

由于我使用的是python 3.4，我尝试了

sudo port install py34-matplotlib +cairo+gtk2

安装顺利，但是当我在PyCharm内的Python控制台上尝试import matplotlib时，出现以下错误：

Backend GTKCairo is interactive backend. Turning interactive mode on.
Failed to enable GUI event loop integration for 'gtk'
Traceback (most recent call last):
  File "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydev_console_utils.py", line 498, in do_enable_gui

  File "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydev_import_hook.py", line 21, in do_import

  File "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydev_ipython/inputhookgtk.py", line 19, in <module>
import gtk, gobject

module = self._system_import(name, *args, **kwargs)
ImportError: No module named 'gtk'

可能是什么问题？
我无法在PyCharm中找到任何gtk模块，但我找到PyGTK，PyGTKCodeBuffer，PyGTKImageView等。是否有任何网站对于gtk模块？

我通过在Interactive : True文件中添加matplotlibrc解决了这个问题。

以下内容：

 import matplotlib.pyplot as plt

并打开一个图形窗口（对我而言，它隐藏在我的IDE背后的背景中，所以起初我以为没有发生任何事情）

Answer 2

对于像我这样使用IPython的用户，您可以输入：

%matplotlib auto

在Linux和MacOS上均可使用。

Answer 3

你写的是这篇文章： ply.show（）

正确的形式是plt.show（）。这是你的错误吗？或者你只在这篇文章上写错了

Answer 4

为什么使用带anaconda的端口？

在您的conda环境中（即从命令行source activate my_env键入，其中my_env是您的环境的名称）：

condo update conda
conda install matplotlib
conda install pyqt

matplotlib挂在mac osx上，不显示图形
