SNPE的Caffe的AlexNet模型转换DLC失败

[开心的小妮]

你好，我下载了最新版的SNPE，在Mac环境下，在转换Caffe模型为DLC格式时出错，参照文档的执行流程，过程代码如下：

虽然问题已经过去很久了，算给后来也遇到同样问题而进入里的人看的吧： 错误提示是文件不存在，其实说的这个文件不是caffe文件，而是SNPE SDK Model Converter的脚本snpe-caffe-to-dlc找不到。 解决办法是设置PYTHONPATH环境变量，export PYTHONPATH=$SNPE_ROOT/bin//x86_64-linux-clang/:$PATH ，其中$SNPE_ROOT是你的SDK根目录

这块它会下载Caffe相关的几个模型的，然后加载一个动态库来生成dlc文件。官网有教学流程，建议先按流程走，出错了看下脚本挂在哪里了。
