深度学习框架caffe在macOS Heigh Sierra上安装过程实录

第一步、安装依赖库

brew install -vd snappy leveldb gflags glog szip lmdb
brew tap homebrew/science
brew install hdf5 opencv
brew install protobuf boost

第二步、编译caffe

git clone https://github.com/BVLC/caffe.git
cd caffe
make all && make test && make runtest

问题一：

in file included from src/caffe/common.cpp::
In file included from ./include/caffe/common.hpp::
./include/caffe/util/device_alternate.hpp::: fatal error: 'cublas_v2.h' file not found
#include <cublas_v2.h>
^~~~~~~~~~~~~
 error generated.

解决方案：
设置Makefile.config中取消注释CPU_ONLY := 1前面的注释

问题二：

./include/caffe/util/mkl_alternate.hpp::: fatal error: 'cblas.h' file not found
#include <cblas.h>

解决方案：
第1步：brew install homebrew/science/openblas
第2步：
修改Makefile.config文件中BLAS:= atlas为BLAS := OpenBlas
修改Makefile.config文件中BLAS的库或头文件：
BLAS_INCLUDE := /usr/local/opt/openblas/include
BLAS_LIB := /usr/local/opt/openblas/lib

问题三：

No receipt for 'com.apple.pkg.CLTools_Executables' found at '/'.
/bin/sh: line : [: -gt: unary operator expected
/bin/sh: line : [: -gt: unary operator expected
LD -o .build_release/lib/libcaffe.so.1.0.
clang: warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument]
ld: framework not found vecLib
clang: error: linker command failed with exit code  (use -v to see invocation)
make: *** [.build_release/lib/libcaffe.so.1.0.] Error 

解决方案：
在命令行中输入：xcode-select --install

第三步、编译pycaffe

make pycaffe

问题一：

CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp
python/caffe/_caffe.cpp::: fatal error: 'numpy/arrayobject.h' file not found
#include <numpy/arrayobject.h>
^~~~~~~~~~~~~~~~~~~~~
 error generated.
make: *** [python/caffe/_caffe.so] Error 

解决方案：
第1步：brew install numpy
第2步：

修改Makefile.config

去掉注释

# PYTHON_INCLUDE += $(dir $(shell python -c 'import numpy.core; print(numpy.core.__file__)'))/include
# PYTHON_LIB += $(shell brew --prefix numpy)/lib

变为

PYTHON_INCLUDE += $(dir $(shell python -c 'import numpy.core; print(numpy.core.__file__)'))/include
PYTHON_LIB += $(shell brew --prefix numpy)/lib

问题二：

ld: library not found for -lboost_python
clang: error: linker command failed with exit code  (use -v to see invocation)
make: *** [python/caffe/_caffe.so] Error 

解决方案:
brew install boost-python

安装caffe的python依赖：
cd python
for req in $(cat requirements.txt); do pip install --user $req; done
