读Resnet.prototxt错误 #11

Closed dimens66 closed 7 years ago

dimens66 commented 7 years ago

你好，请教一个问题。我在读Resnet.prototxt时发生了错误。我编的是arm-v7a的so，另外采用新版本的工具转换成binayproto也没有成功。目前读cifar10.prototxt可以，但是读resnet不行。在pc上读同样的模型都没有问题，只要放在android上就不行。请问这是什么原因？

错误定位： net_.reset(new Net(param_file, caffe::TEST)); 这一句跑不过。 进net构造函数中，定位到是最后一个函数Init(param);中crash。目前暂未找到问题在哪。

@ChangyeGuo 把 prototxt 文件作为附件上传上来吧，我试着看下。

@solrex 附件没法上传，我分享到了百度网盘了。麻烦看一下。 链接：http://pan.baidu.com/s/1c2zRuy0 密码：mhd0

@ChangyeGuo 抱歉，我当初只关注了 layer_factory.cpp 里列出的 layer，遗漏了一些 resnet 依赖的 layer。我已补充这些 layer https://github.com/solrex/caffe-mobile/commit/326fe37f02f9e25789a2545e34ae101c398a5195 ，自测是没问题了，麻烦更新代码再试一下。

@solrex resnet已经能读取，谢谢。 现更新最新的repo后，编译时发生错误。信息如下： make[1]: Leaving directory `/home/guocy/caffe-mobile-511/third_party/OpenBLAS-0.2.19' CMake Error at /usr/share/cmake-2.8/Modules/CMakeDetermineSystem.cmake:99 (message): Could not find toolchain file: ../third_party/android-cmake/android.toolchain.cmake Call Stack (most recent call first):

问题分析：初步分析应该是build-protobuf-3.1.0.sh的136行： ln -sf ../../protobuf-Linux/bin/protoc protoc 没有软链接成功。我把这一句comment，再把/Linux-protobuf/bin/protoc拷贝到android-protobuf文件夹下，然后就可以编译了。 请修复。 BEST LUCK!!!

build-protobuf-3.1.0.sh脚本里面function build-Android 里面缺少了个cd ..造成cmake路径不对，还有这个软连接不对，文件夹名字错了，正确的是ln -sf ../../Linux-protobuf/bin/protoc protoc
