如何在Windows 8计算机上保存模型?

How can I save my model on my Windows 8 machine?

更新:此命令似乎在此处创建文件夹&文件:

UPDATE:This command here seems to create a folder & file:

这创建了一个文件:C:/temp/DeepLearningModel__8412f3ab21699b5593aa5c6861c8468d.bin但是随后引发了另一个错误:

This created a file: C:/temp/DeepLearningModel__8412f3ab21699b5593aa5c6861c8468d.binBut then throws a different error:
