Python Tkinter 导入文件对话框错误

Tkinter import filedialog error

提问by Rémi Vennereau

I'm trying to use tkinter with python3 to open an image, see here a piece of code :

我正在尝试将 tkinter 与 python3 一起使用来打开图像，请参阅此处的一段代码：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# --- Python 3.4

from PIL import Image
import Tkinter as tk
from Tkinter import filedialog
import numpy as np
import os
var = 'n'

# Importing the image to correct

while var != 'o' :
    var = raw_input("Press \"o\" to open the image to correct\n")
    var = var.lower()
root = tk.Tk()
root.withdraw()
path = filedialog.askopenfilename()
image_test = Image.open(path)

I have installed python3-tk, and I have the demo window when I write

我已经安装了python3-tk，我写的时候有演示窗口

python3 -m tkinter 

in the terminal. I tried several combinations that did not work :

在终端。我尝试了几种不起作用的组合：

import tkinter as tk
from tkinter import filedialog

gives

给

ImportError : No module named tkinter

,

,

import Tkinter as tk
from Tkinter import filedialog    

gives

给

ImportError : cannot import name filedialog

I tried with _tinker , FileDialog, file_dialog, but I always have "ImportError : cannot import name filedialog". Any clue ?

我尝试过 _tinker 、 FileDialog、file_dialog，但我总是有“ImportError : cannot import name filedialog”。任何线索？

tkinter.filedialogis for Python 3 only.

tkinter.filedialog仅适用于 Python 3。

From your attempts, it seems like you are using Python 2.x, try importing tkFileDialog

从您的尝试来看，您似乎正在使用Python 2.x，请尝试导入tkFileDialog

Example -

例子 -

import tkFileDialog as filedialog

Or alternatively, check why it ends up running Python 2.x , instead of Python 3.x .

或者，检查为什么它最终运行 Python 2.x 而不是 Python 3.x 。

Tkintermodule is only there in python 2 , python 3 has tkintermodule, since when importing Tkinterit is successfully getting imported, but when importing tkinterit is failing to import it, we can be sure you end up running Python 2.x and not Python 3.

Tkinter模块只存在于 python 2 中，python 3 有tkinter模块，因为在导入Tkinter时成功导入，但在导入时导入tkinter失败，我们可以确定您最终运行的是 Python 2.x 而不是 Python 3。

You can do -

你可以做 -

import sys
print(sys.version)
print(sys.executable)

to check the version of python currently running as well as the location of python(or python3) that is running.

检查当前运行的python版本以及正在运行的python（或python3）的位置。

Most probably , the issue is occuring because even though you have python3shebang line in your script, you are most probably running python <script.py>, this always causes python 2 to run.

最有可能的是，问题的发生是因为即使python3您的脚本中有shebang 行，您也很可能正在运行python <script.py>，这总是会导致 python 2 运行。

The aim of adding the python3shebang line was to be able to run the script directly, without specifying the executable. For that you would need to do -

添加python3shebang 行的目的是能够直接运行脚本，而无需指定可执行文件。为此，你需要做 -

1. Give executable permission to the script. (Use chmod u+x <script.py>)
2. Then run the script as - ./<script.py>

1. 授予脚本可执行权限。（使用chmod u+x <script.py>）
2. 然后将脚本运行为 - ./<script.py>

It should be from tkinter import filedialogalternatively you can try from tkinter import *or import tkinter.filedialog as fd. If it doesn't work like that, then you should try to reinstall python.

应该from tkinter import filedialog或者你可以尝试from tkinter import *或import tkinter.filedialog as fd。如果它不起作用，那么您应该尝试重新安装python。
