这里我们安装openblas主要有两种方法:

1. 通过git代码到本地并安装
2. 通过brew来安装

git到本地编译安装.

1. git代码到本地并安装

git clone https://github.com/xianyi/OpenBLAS.git
cd OpenBLAS
make -j4
make install

1. 修改Caffe的Makefile.config

BLAS := open
BLAS_INCLUDE :=  /opt/OpenBLAS/include
BLAS_LIB := /opt/OpenBLAS/lib

1. caffe重新make

make clean
make pycaffe
make all -j4
make test && runtest

使用brew进行安装

1. brew uninstall openblas; brew install --fresh -vd openblas.运行上面命令安装openblas
2. 更改Makefile.config

# Homebrew puts openblas in a directory that is not on the standard search path
BLAS_INCLUDE := $(shell brew --prefix openblas)/include
BLAS_LIB := $(shell brew --prefix openblas)/lib

1. 重新编译

如果有些人遇到了这种错误

         ^

make: *** [.build_release/src/caffe/util/blocking_queue.o] Error 1

可以试试这个命令:

cmake -DCMAKE_CXX_FLAGS=-I/usr/local/opt/openblas/include ..
