我在使用 filedialog 调整图像大小时遇到问题。from PIL import Image, ImageTkdef fileDialog(self): self.filename = filedialog.askopenfilename(title="Select file") self.label = tk.Label(self.labelFrame, text = "") self.label.grid(column = 1, row = 2) self.label.configure(text=os.path.basename(self.filename)) self.img = Image.open(self.filename) self.resized_img = self.img.resize((200, 100)) self.photo = ImageTk.PhotoImage(file=self.resized_img) self.display = tk.Label(image=self.photo) self.display.grid(row=0)我在 filedialog 函数中执行此操作的原因是因为在用户单击文件之前我不知道将选择的文件的名称。我这样做Image.open(self.filename)是因为filename保存了文件浏览器打开后用户单击的文件的名称。但是,我得到了这些错误。我不想这样做,open('car.jpg')因为这可能是一个不同的画面,这就是我这样做的原因open('self.filename')。Traceback (most recent call last):File "C:\Users\AppData\Local\Programs\Python\Python37- 32\lib\tkinter\__init__.py", line 1705, in __call__return self.func(*args)File "gui.py", line 41, in fileDialogself.photo = ImageTk.PhotoImage(file=self.resized_img)File "C:\Users\AppData\Local\Programs\Python\Python37-32\lib\site- packages\PIL\ImageTk.py", line 94, in __init__image = _get_image_from_kw(kw)File "C:\Users\AppData\Local\Programs\Python\Python37-32\lib\site- packages\PIL\ImageTk.py", line 64, in _get_image_from_kwreturn Image.open(source)File "C:\Users\AppData\Local\Programs\Python\Python37-32\lib\site- packages\PIL\Image.py", line 2661, in openprefix = fp.read(16) AttributeError: 'Image' object has no attribute 'read' Exception ignored in: <function PhotoImage.__del__ at 0x03A63B70> Traceback (most recent call last): File "C:\Users\AppData\Local\Programs\Python\Python37-32\lib\site- packages\PIL\ImageTk.py", line 123, in __del__ name = self.__photo.name AttributeError: 'PhotoImage' object has no attribute '_PhotoImage__photo'我收到此错误是否有原因?请指教。
