我寫了一個面部識別程序，現(xiàn)在我必須為它制作一個 GUI。我需要做的是顯示5張已識別人物的圖像。但我只能顯示其中一個。其他顯示為空。這是代碼：root = Tk()root.title("Test state")def train_button(): os.system('python3 extract_embeddings.py --dataset dataset --embeddings output/embeddings.pickle --detector face_detection_model --embedding-model openface_nn4.small2.v1.t7') os.system('python3 train_model.py --embeddings output/embeddings.pickle --recognizer output/recognizer.pickle --le output/le.pickle') messagebox.showinfo("INFO","Training completed")def select_photo(): global my_image root.filename = filedialog.askopenfilename(initialdir="test",title ="Select a photo",filetypes=(("all files","*.*"),("png files","*.png"),("jpeg files","*.jpeg"))) output = subprocess.check_output("python3 recognize.py --detector face_detection_model --embedding-model openface_nn4.small2.v1.t7 --recognizer output/recognizer.pickle --le output/le.pickle --image "+root.filename, shell=True) output = output.decode('utf-8') pic_name = output.split('\n')[0] my_image = ImageTk.PhotoImage(Image.open("images/"+pic_name+"/"+pic_name+"1.jpeg")) my_image_label = Label(image = my_image).grid(row = 1 ,column = 0) name_label = Label(text = pic_name).grid(row=2,column=0) my_image1 = ImageTk.PhotoImage(Image.open("images/"+pic_name+"/"+pic_name+"2.jpeg")) my_image_label1 = Label(image = my_image1).grid(row =1 ,column=1) my_image2 = ImageTk.PhotoImage(Image.open("images/"+pic_name+"/"+pic_name+"3.jpeg")) my_image_label2 = Label(image = my_image2).grid(row = 1,column = 2)button1 = Button(root,text = "Train" , command = train_button).grid(row=0 ,column=0)button2 = Button(root,text = "Recognise from image", command = select_photo).grid(row = 0 ,column=1)root.mainloop()這就是程序顯示圖像的方式 結(jié)果程序

PhotoImage這是在將圖像分配給函數(shù)中的局部變量時刪除圖像的錯誤。
你必須將它分配給全局變量（如果你有很多圖像，它可以是列表）或分配給你用來顯示它的小部件 -label.photo = image
我可以測試它，但這是用于label.photo = image解決此問題的版本
它還使用for-loop 來創(chuàng)建標(biāo)簽并將它們保存在列表中。
但是當(dāng)你使用label.photo = imagethen list 是沒有必要的。List 僅用于訪問標(biāo)簽以在創(chuàng)建新標(biāo)簽之前刪除舊標(biāo)簽。
