Question

我正在尝试在Tkinter画布中显示图像以及一些文本，并且遇到以下错误。另外，在anaconda中使用Spyder（最新的Spyder）运行时，我的mac机不显示按钮的背景色。

我的python代码是：

from tkinter import *  
from PIL import ImageTk,Image  

def plot_best_batsmen():
    best_batsmen = dataset.loc[dataset.loc[dataset['Innings']>=15,'Average'].idxmax(),'Names']
    message = ("The best Batsman of the Tournament could possibly be: ", best_batsmen)
    canvas_width = 500
    canvas_height = 500
    root = Tk()
    root.geometry("600x600")
    root.title("New Window")
    canvas = Canvas(root, width=canvas_width, height=canvas_height)
    canvas.create_text(1, 10, anchor=W, text=message)
    img = ImageTk.PhotoImage(Image.open("prediction.jpg"))
    canvas.create_image(20, 20, anchor=NW, image=img)
    canvas.image = img
    canvas.pack()
    root.mainloop()

运行时显示如下错误消息：

Exception in Tkinter callback
Traceback (most recent call last):
  File "/anaconda3/lib/python3.7/tkinter/__init__.py", line 1705, in __call__
    return self.func(*args)
  File "/Users/vivekchowdary/Documents/PS3_Final_Project/Batsmen.py", line 110, in plot_best_batsmen
    canvas.create_image(20, 20, anchor=NW, image=img)
  File "/anaconda3/lib/python3.7/tkinter/__init__.py", line 2489, in create_image
    return self._create('image', args, kw)
  File "/anaconda3/lib/python3.7/tkinter/__init__.py", line 2480, in _create
    *(args + self._options(cnf, kw))))
_tkinter.TclError: image "pyimage3" doesn't exist

按钮代码如下：

b1 = Button(root, text="Elbow Method", command=plot_elbow, bg="green", fg="white").pack(side = LEFT)
b2 = Button(root, text="K-Means Clustering", command=plot_kmeans, bg="blue", fg="white").pack(side = LEFT)
b3 = Button(root, text="Batsmen who scored 4 or more Hundreds", command=plot_hundreds, bg="#D35400", fg="white").pack(side = LEFT)
b4 = Button(root, text="Runs Scored by Various Players", command=plot_runs, bg="#117A65", fg="white").pack(side = LEFT)
b5 = Button(root, text="Best Batsmen", command=plot_best_batsmen, bg="#34495E", fg="white").pack(side = LEFT)
b6 = Button(root, text="Stop", command=root.destroy, bg="red", fg="white").pack(side = BOTTOM)

我希望Tkinter显示以下图像。但是它正在报告一个错误。谁能帮我解决这个错误？

Answer 1

tkinter也有一个称为Image的类/函数。您还从PIL导入了图像。您需要确定要使用的Image.open。 tkinter.Image没有'open'属性。

Answer 2

似乎该错误与您的tkinter无关。要确定问题所在，请

from PIL import Image 
print(Image.open)

如果正确安装了所有内容，结果应类似于以下内容。

< function open at 0x0000000008A26488 >

Answer 3

我自己想出了答案，只是想分享它来帮助有同样疑问的人。

我们需要在Tkinter之后导入PIL，因为Tkinter也有自己的类Image，该类不具有“打开”功能，并且如果在PIL之后导入，则来自Tkinter的Image会替换来自PIL的Image。

，第二件事是将root = Tk()替换为root = Toplevel()，因为问题是当Python / Tkinter试图从按钮创建画布时，它实际上是在试图创建两个窗口在根下倒下。

现在，代码将照片导入到GUI中并且可以正常工作。

所以，下面的代码终于可以正常工作了： def plot_best_batsmen(): best_batsmen = dataset.loc[dataset.loc[dataset['Innings']>=15,'Average'].idxmax(),'Names'] message = ("The best Batsman of the Tournament could possibly be: ",best_batsmen) canvas_width = 400 canvas_height = 500 root = Toplevel() root.geometry("700x600") root.title("New Window") canvas = Canvas(root, width=canvas_width, height=canvas_height) canvas.create_text(1, 10, anchor=W, text=message) img = ImageTk.PhotoImage(Image.open("virat.jpg")) canvas.create_image(150, 20, anchor=NW, image=img) canvas.image = img canvas.pack() root.mainloop()

如何解决python中的错误“ AttributeError：类型对象'Image'没有属性'open'”？
