我对cntk完全陌生。我最近使用 GeForce 940MX GPU 在我的电脑(Windows 10,i5-7200U CPU)上安装了 cntk 2.7(GPU 版本)。我正在尝试设置 cntk 和以下链接中提供的更快的 rcnn 对象检测示例 https://docs.microsoft.com/en-us/cognitive-toolkit/object-detection-using-faster-r-cnn

我正在尝试运行玩具示例。

在 Examples/Image/Detection/FastRCNN 文件夹中运行 install_data_and_model.py 后

我运行 run_faster_rcnn.py Examples/Image/Detection/FasterRCNN 文件夹

我收到以下错误:

Selected GPU[0] GeForce 940MX as the process wide default device.

有人可以帮我解决问题的全部内容吗?

保存最后一个模型时关闭cntk时总是发生此错误,因此模型文件中断
