我正在构建一个将matplotlib图形嵌入GUI的应用程序。问题是,只要我在代码中添加来自matplotlib的任何内容(除了导入之外,那些像往常一样工作),我的应用程序就会崩溃。问题出现在我的类Solver_App
中的tk.Tk.__init__(self, *args, **kwargs)
。运行代码时,我会得到一个庞大的错误,并且应用程序会崩溃。以下是我的一些代码:
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()
以下是运行代码时出现的大量错误:

libc++abi.dylib: terminating with uncaught exception of type NSException
我一直在参考一个教程中的代码,[此处](http://pythonprogramming.net/how-to-embed-matplotlib-graph-tkinter-gui/"如何将Matplotlib图形嵌入到Tkinter GUI中")他们的示例似乎可以正常工作。是什么原因导致了这个问题,怎样才能解决?
- 我正在使用Python 3.4、matplotlib 1.4.3,运行Mac OS Yosemite。
pyplot
,而是使用你已经导入的实际的Figure
。你跳过了我们可以看到你是否这样做的地方。 - Ajeanplt.rcParams['keymap.save'] = ''
这可能是由于Mac的键绑定方式导致的。上次我在Mac上使用tkinter时,如果出现NSException异常,那是因为tkinter和Mac的键绑定方式冲突了。 - Pythonista
