python - _tkinter.TclError：图像“pyimage”不存在

问题描述

在我开始之前，是的，我已经查看了所有之前提出的问题，但我似乎找不到答案，所以我有这段代码，我正在使用 Tkinter，并且代码本身运行得很好。

然后我创建另一个文件来调用这个特定的文件，我得到_tkinter.TclError: image "pyimage" doesn't exist.

我不知道为什么它自己工作但调用时失败。

调用类：

from tkinter import *
from PIL import Image
from PIL import ImageTk
from tkinter import ttk
#import all classes
from tests.rpm import *
from tests.bst import *
from tests.gdt import *

#results to store on cloud
RPMresult = BSTresult = GDTresult = VLresult = 0

def RPMCALL():
    root = Tk()
    w = 500 # width for the Tk root
    h = 500 # height for the Tk root
    # get screen width and height
    ws = root.winfo_screenwidth() # width of the screen
    hs = root.winfo_screenheight() # height of the screen
    # calculate x and y coordinates for the Tk root window
    x = (ws/2) - (w/2)
    y = (hs/2) - (h/2)
    # set the dimensions of the screen
    # and where it is placed
    root.geometry('%dx%d+%d+%d' % (w, h, x, y))
    RPMcall = RPM(root,6)
    root.mainloop()
    global RPMresult
    RPMresult=RPMcall.getresult()

def BSTCALL():
    root = Tk()
    w = 500 # width for the Tk root
    h = 500 # height for the Tk root
    # get screen width and height
    ws = root.winfo_screenwidth() # width of the screen
    hs = root.winfo_screenheight() # height of the screen
    # calculate x and y coordinates for the Tk root window
    x = (ws/2) - (w/2)
    y = (hs/2) - (h/2)
    # set the dimensions of the screen
    # and where it is placed
    root.geometry('%dx%d+%d+%d' % (w, h, x, y))
    BSTcall = BST(root,6)
    root.mainloop()
    global BSTresult
    BSTresult=BSTcall.getresult()

def GDTCALL():
    root = Tk()
    w = 500 # width for the Tk root
    h = 500 # height for the Tk root
    # get screen width and height
    ws = root.winfo_screenwidth() # width of the screen
    hs = root.winfo_screenheight() # height of the screen
    # calculate x and y coordinates for the Tk root window
    x = (ws/2) - (w/2)
    y = (hs/2) - (h/2)
    # set the dimensions of the screen
    # and where it is placed
    root.geometry('%dx%d+%d+%d' % (w, h, x, y))
    GDTcall = GDT(root,6)
    root.mainloop()
    global GDTresult
    GDTresult=GDTcall.getresult()


RPMCALL()
BSTCALL()
GDTCALL()

解决方案

我遇到了同样的问题，但只是在使用 spyder 时（在 eclipse 中使用 pydev 没有问题）。我为自己找到了两个对我有用的解决方案。

解决方案 1：转到 Tools => Preferences 并选择左侧的 IPython 控制台。在 IPython 控制台菜单中选择图形选项卡并禁用顶部的复选框“活动支持”（支持图形）。在运行代码之前保存并重新启动内核

解决方案2：转到运行=>配置并选择“在外部系统终端中执行”，保存并运行代码

如上所述，两种解决方案都适用于我的问题。
