Matplotlib崩潰tkinter應用程序

我正在構建一個將matplotlib圖嵌入到GUI中的應用程序。問題是，一旦我從matplotlib添加了任何東西到我的代碼中（除了導入，那些工作像往常一樣），我的應用就崩潰了。問題發生在我的課Solver_App在tk.Tk.__init__(self, *args, **kwargs)。當我運行代碼時，出現大量錯誤，應用程序崩潰。下面是我的一些代碼：Matplotlib崩潰tkinter應用程序

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()

這裏是巨大的錯誤運行代碼時，我得到：

我已經從一個教程[這裏找到]引用代碼（http://pythonprogramming.net/how-to-embed-matplotlib-graph-tkinter-gui/「如何嵌入一個Matplotlib圖形到你的Tkinter GUI「），但他們的例子似乎工作正常。造成這個問題的原因是什麼？如何解決？

我使用Python 3.4，matplotlib 1.4.3，並運行Mac OS Yosemite。

我覺得你已經省略了最重要的部分。看看你是否可以把它提煉成一個[MCVE]（http://stackoverflow.com/help/mcve），它可能會幫助你解決你的問題。一個技巧，當你這樣做：當在Tkinter中嵌入東西時，不要使用'pyplot';使用你輸入的實際的'圖'。如果你正在做或不做，你跳過了我們可以看到的地方。 – Ajean

請嘗試執行以下操作。 'plt.rcParams ['keymap.save'] ='''這可能是mac擁有鍵綁定的結果。上次我在Mac上由tkinter引發了一個NSException，這是由於tkinter和mac與它們的鍵綁定相沖突的結果。 – Pythonista

您需要明確設置TkAgg後端。我可以重現你的錯誤。使用下面的代碼，問題就解決了。

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

注意，設置TkAgg後端進口pyplot無法正常工作或之後;它也崩潰了。您需要在導入pyplot之前設置它。（經過MPL 1.4.3，tkinter.TkVersion 8.6測試）

固定對我來說 - 測試與mpl 1.5.1，tkinter.TkVersion 8.5 – theicfire

就像一個魅力！謝謝。 – Rynkadink
