<p>我正在构建一个将matplotlib图形嵌入到GUI中的应用程序。问题是,只要我将matplotlib中的任何内容添加到代码中,我的应用程序就会崩溃(除了导入之外,那些工作正常)。问题出现在我的类<code>Solver_App</code>中的<code>tk.Tk.__init__(self, *args, **kwargs)</code>。当我运行代码时,我得到一个巨大的错误和应用程序崩溃。以下是我的一些代码:</p>
<pre><code>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()

<p>下面是运行代码时出现的巨大错误:</p>

<p>我引用了一个教程中的代码(如何将Matplotlib图嵌入到Tkinter GUI中),但是他们的例子似乎工作得很好。是什么导致了这个问题,如何解决?</p>
<ul>
<li>我使用的是Python3.4,MatplotLib1.4.3,运行的是MacOSYosemite。</li>
