person search project failed to compile caffe with cudnn

[tonywang-sh]

I met an issue about compiling this caffe branch with cudnn. as mentioned in person search wiki. it used cudnn-5.1, but compiling this caffe branch failed with both cuda 8.0's and cuda7.5's cudnn 5.1. what about the exact cudnn version for compiling this caffe branch.

the below is a part of error message,

Did you build in CPU_ONLY mode? It is a known issue #21. Please try to compile it with -DUSE_MPI=ON.

[tonywang-sh]

I tried CPU_ONLY mode with -DUSE_MPI=ON, there are still some error messages, my OS is centos 7.

Well, #25 seems to be the same issue. Please refer to that thread, and I will ask the author how he has solved it.

[tonywang-sh]

@Cysu in order to compile this caffe branch, can we use make with Makefile.config directly. If so, how to set USE_MPI option into compiling process

[Cysu]

@TonnyWang Sorry but the caffe cannot be compiled with Makefile.config. We must use cmake for compiling. Please try the following commands.

cd caffe
mkdir build && cd build
cmake .. -DUSE_MPI=ON -DCUDNN_INCLUDE=/path/to/cudnn/include -DCUDNN_LIBRARY=/path/to/cudnn/lib64/libcudnn.so
make -j8 && make install
cd ../..
