运行时错误:无法从输入流分析字典

Question

我是cntk的新手。我最近在装有GeForce 940MX GPU的电脑上安装了cntk 2.7(GPU版本((Windows 10，i5-7200U CPU(。我正在尝试设置 cntk 和下面链接中提供的更快的 rcnn 对象检测示例https://learn.microsoft.com/en-us/cognitive-toolkit/object-detection-using-faster-r-cnn

我正在尝试运行玩具示例。

在示例/图像/检测/快速RCNN文件夹中运行install_data_and_model.py后

我运行run_faster_rcnn.py示例/图像/检测/更快的RCNN文件夹

我收到以下错误：

有人可以帮助我解决问题吗？

当您

在保存最后一个模型时关闭cntk时，总是会发生此错误，因此模型文件中断
