我正在虚拟环境中使用flask.我能够用pip安装matplotlib,我可以import matplotlib在Python会话中.但是,当我导入它时

matplotlib.pyplot as plt

我收到以下错误:

>>> import matplotlib.pyplot as plt

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/envs/myenv/lib/python2.7/site-packages/matplotlib/pyplot.py", line 109, in <module>

我收到此错误:

/sw/lib/python2.7/site-packages/matplotlib/backends/backend_macosx.py:235:UserWarning:Python未作为框架安装.如果未将Python安装为框架,则MacOSX后端可能无法正常工作.有关在Mac OS X上安装Python作为框架的更多信息,请参阅Python文档

我使用fink安装了python27,并且使用默认的matplotlib是使用macosx框架.

之前已经问过这个问题,在这里,也在这里.但是,解决方案并没有解决我的问题.

最初的错误是,当我尝试时import matplotlib.pyplot,我得到:

回溯(最近一次调用最后一次):文件"",第1行,文件"/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/pyplot.py",第114行,在_backend_mod,new_figure_manager中, draw_if_interactive,_show = pylab_setup()文件"/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/backends/ INIT py"为32行,在pylab_setup全局(),当地人(),[backend_name ],0)文件"/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_macosx.py",第24行,来自matplotlib.backends import _macosx RuntimeError:Python未安装为框架.如果未将Python安装为框架,则Mac OS X后端将无法正常运行.有关在Mac OS X上安装Python作为框架的更多信息,请参阅Python文档.请重新安装Python作为框架,或尝试其他后端之一.如果您在虚拟环境中使用Matplotlib,请参阅Matplotlib中的"在虚拟环境中使用Matplotlib"常见问题解答

我按照解决方案添加了一个~/.matplotlib/matplotlibrc包含以下代码的文件:backend: TkAgg.这样做之后,我的错误变为:

/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/font_manager.py:273:UserWarning:Matplotlib正在使用fc-list构建字体缓存.这可能需要一点时间.warnings.warn('Matplotlib正在使用fc-list构建字体缓存.这可能需要一些时间.')objc [25120]:类TKApplication在/Users/XX/anaconda/lib/libtk8.5.dylib和/ /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk.将使用两者之一.哪一个未定义.objc [25120]:类TKMenu在/Users/XX/anaconda/lib/libtk8.5.dylib和/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk中实现.将使用两者之一.哪一个未定义.objc [25120]:类TKContentView在/Users/XX/anaconda/lib/libtk8.5.dylib和/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk中实现.将使用两者之一.哪一个未定义.objc [25120]:类TKWindow在/Users/XX/anaconda/lib/libtk8.5.dylib和/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk中实现.将使用两者之一.哪一个未定义.

我不知道如何解决这个问题.我没有使用虚拟机.你可以帮帮我吗？谢谢!

PS:我发现通过添加:

import matplotlib
matplotlib.use('TkAgg')

之前import matplotlib.pyplot,它似乎工作.但每次添加这两行代码都很烦人...有谁知道发生了什么以及如何解决它？谢谢!

我用pkg安装程序安装了Anaconda:

但是当我尝试使用matplotlib中的任何东西时,即:

 from matplotlib import pyplot as plt

我明白了

我正在关注scikit文档的决策树教程.我有,pydotplus 2.0.2但它告诉我它没有write方法 - 错误如下.我现在一直苦苦挣扎,有什么想法,好吗？非常感谢!

from sklearn import tree

iris = load_iris()
clf = tree.DecisionTreeClassifier()

from IPython.display import Image

graph = pydotplus.graphviz.graph_from_dot_data(dot_data)

Image(graph.create_png())
