Matplotlib崩溃tkinter应用程序

我正在构建一个将matplotlib图嵌入到GUI中的应用程序。问题是，一旦我从matplotlib添加了任何东西到我的代码中（除了导入，那些工作像往常一样），我的应用就崩溃了。问题发生在我的课Solver_App在tk.Tk.__init__(self, *args, **kwargs)。当我运行代码时，出现大量错误，应用程序崩溃。下面是我的一些代码：Matplotlib崩溃tkinter应用程序

import tkinter as tk 
from tkinter import ttk 

import matplotlib 
from matplotlib import pyplot as plt 
from mpl_toolkits.mplot3d import Axes3D 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg 
from matplotlib.figure import Figure 

# Setting up figures for integration in GUI: 
fig_3D = plt.figure() 
fig_2D = plt.figure() 
a_3D = fig_3D.add_subplot(111, projection="3d") 
a_2D = fig_2D.add_subplot(111) 
a_3D.plot_wireframe([1, 2, 3, 4, 5], [1, 3, 7, 6, 4], [1, 2, 3, 4, 5], color="blue") 

class Solver_App(tk.Tk, ttk.Frame): 

    def __init__(self, *args, **kwargs): 

     tk.Tk.__init__(self, *args, **kwargs) # This is where the app crashes. 

     # Equation frame holds everything related to the input and configuration of the equations. 
     equation_frame = ttk.Frame(self) 
     equation_frame.pack(side="bottom", fill="x", pady=50, padx=50) 

     # More code goes here... 

# There are more classes with a similar setup as the one above... 

app = Solver_App() 
app.mainloop()

这里是巨大的错误运行代码时，我得到：

我已经从一个教程[这里找到]引用代码（http://pythonprogramming.net/how-to-embed-matplotlib-graph-tkinter-gui/“如何嵌入一个Matplotlib图形到你的Tkinter GUI“），但他们的例子似乎工作正常。造成这个问题的原因是什么？如何解决？

我使用Python 3.4，matplotlib 1.4.3，并运行Mac OS Yosemite。

我觉得你已经省略了最重要的部分。看看你是否可以把它提炼成一个[MCVE]（http://stackoverflow.com/help/mcve），它可能会帮助你解决你的问题。一个技巧，当你这样做：当在Tkinter中嵌入东西时，不要使用'pyplot';使用你输入的实际的'图'。如果你正在做或不做，你跳过了我们可以看到的地方。 – Ajean

请尝试执行以下操作。 'plt.rcParams ['keymap.save'] ='''这可能是mac拥有键绑定的结果。上次我在Mac上由tkinter引发了一个NSException，这是由于tkinter和mac与它们的键绑定相冲突的结果。 – Pythonista

您需要明确设置TkAgg后端。我可以重现你的错误。使用下面的代码，问题就解决了。

import matplotlib 
matplotlib.use("TkAgg") 
from matplotlib import pyplot as plt

注意，设置TkAgg后端进口pyplot无法正常工作或之后;它也崩溃了。您需要在导入pyplot之前设置它。（经过MPL 1.4.3，tkinter.TkVersion 8.6测试）

固定对我来说 - 测试与mpl 1.5.1，tkinter.TkVersion 8.5 – theicfire

就像一个魅力！谢谢。 – Rynkadink
