更新：想出了一个解决方案并更新为一个自我回答。
我在一个目录中有 20 张 jpg 图像。使用 Python 3.7 + Tkinter 8.6.10。我访问它们，调整大小并将它们显示在 aa 网格的主窗口中。网格有 12 行 x 5 列 = 60 帧。第 1 行中的所有帧都具有填充有调整大小图像的标签。第 2 行中的所有框架都有带有文本“放大”的标签。第 3 行中的所有框架都有带有文本“选择”的标签。这种模式重复。
单击“放大”按钮时，我想在新窗口中显示完整的未调整大小的图像。我在显示放大图像时遇到问题。一个新窗口打开，但没有图像。我在控制台中收到以下错误：-------------------- 控制台输出开始 ------------------ --
