label1 = Label(app, textvariable=labelText, height=4)
label1.pack()
#checkBoxVal = IntVar()
#checkBox1 = Checkbutton(app, variable=checkBoxVal, text="Hello?")
#checkBox1.pack()
custom = StringVar(None)
legend = Entry(app, textvariable=custom)
legend.pack()
button1 = Button(app, text='Click to fetch URIs', width=20, command=FetchURI)
button1.pack(side='top', padx=15 , pady=15)
app.mainloop()
該功能屬於Tkinter GUI,我認為它與此無關。 我也很難理解這個相當愚蠢的錯誤。 URIs.txt
文件存在於Imagenet
目錄中,因此此處某些其他地方必須出錯。 也許for
循環或f.readlines
?
任何反饋?

請檢查/home/nick/Desktop/Imagenet/URIs.txt
文件是否存在? 如果存在,那么它是否有權閱讀?
