Matplotlib 崩溃 tkinter 应用程序 [英] Matplotlib Crashing tkinter Application
问题描述
我正在构建一个将 matplotlib 图形嵌入 GUI 的应用程序.问题是,只要我将 matplotlib 中的任何内容添加到我的代码中,我的应用程序就会崩溃(导入除外,它们照常工作).问题发生在我的 tk.Tk.__init__(self, *args, **kwargs)
班级 Solver_App
中.当我运行代码时,我收到了一个巨大的错误,应用程序崩溃了.这是我的一些代码:
I am building an application that embeds a matplotlib figure into the GUI. The problem is that my app is crashing as soon as I add anything from matplotlib into my code (except for the imports, those work as usual). The problem occurs in my class Solver_App
at tk.Tk.__init__(self, *args, **kwargs)
. When I run the code, I get a massive error and the app crashes. Here is some of my 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()
这是我在运行代码时遇到的大量错误:
And here is the massive error I get when running the code:

我一直在引用教程中的代码 [在这里找到](http://pythonprogramming.net/how-to-embed-matplotlib-graph-tkinter-gui/"How to embed a Matplotlib graph to your Tkinter GUI"),但他们的例子似乎工作正常.导致此问题的原因是什么?如何解决?
I have been referencing code from a tutorial [found here](http://pythonprogramming.net/how-to-embed-matplotlib-graph-tkinter-gui/"How to embed a Matplotlib graph to your Tkinter GUI"), but their example seems to work fine. What is causing this problem and how can it be fixed?
- 我使用的是 Python 3.4、matplotlib 1.4.3,并运行 Mac OS Yosemite.
推荐答案
您需要明确设置 TkAgg 后端.我可以重现你的错误.使用以下代码,问题解决.
You need to set the TkAgg backend explicitly. I could reproduce your bug. With the following code, the problem is resolved.
import matplotlib
matplotlib.use("TkAgg")
from matplotlib import pyplot as plt
请注意,在导入 pyplot 之后 设置 TkAgg 后端也不起作用;它也会崩溃.你需要在导入pyplot之前设置它.(使用 MPL 1.4.3、tkinter.TkVersion 8.6 测试)
Note that setting the TkAgg backend after importing pyplot does not work either; it crashes too. You need to set it before importing pyplot. (Tested with MPL 1.4.3, tkinter.TkVersion 8.6)
