我是在Windows环境下配置的Caffe，在训练mnist的时候发生这个错误，完整的错误列表如下：

NetParameter file: ./lenet_train_test.prototxt
*** Check failure stack trace: ***

可以看出是解析lenet_train_test.prototxt出错，NetParameter后面跟的是错误的位置，比如第一个是14行17列，找到lenet_train_test.prototxt这个位置发现是’\’。

问题原因：

在windows中路径分隔符是’\’，比如我一开始直接复制lmdb的路径到prototxt中的：

source这个字符串在c里面解析为转义，所以出错。

解决方法：

将‘\’改为‘/’或者‘\\’
