Install Caffe on Mac error: "fatal error: 'cblas.h' file not found"

Install Caffe on Mac error: "fatal error: 'cblas.h' file not found"

我一直在关注 this guide 在我的 El Capitan macbook pro 上安装,使用 CMake 构建 makefile。但是,当我尝试制作时,我 运行 进入了缺少 cblas.h 文件的错误。我成功地重新安装了 openblas:

$ brew uninstall openblas; brew install --fresh -vd openblas

并添加两个构建标志:

LDFLAGS: -L/usr/local/opt/openblas/lib

CPPFLAGS: -I/usr/local/opt/openblas/include

但是我仍然得到错误。然后我重新安装了 CUDA 和 xcode-select 推荐的安装工具 here

任何 recommendations/further 为什么 make 看不到我的 cblas.h 文件的猜测都将受到赞赏!

在你的问题中我看到 cmake,但在提供 link Makefile.config.

如果你还想继续 cmake:

首先,构建脚本没有损坏 - 我在 Yosemite 上使用最新的 master 分支 (2016-02-25) 进行了尝试,但如果你已经这样做了,你应该稍微调整一下制作

brew uninstall openblas; brew install --fresh -vd openblas

只是 运行 你的 cmake 和额外的参数:

cmake -DCMAKE_CXX_FLAGS=-I/usr/local/opt/openblas/include <path to your sources>

然后是通常的 make 或 xcode build(取决于您使用的生成器)。

此后它在我的系统上成功构建。

UPD: 您还可以使用 Accelerate.framework (vecLib) 中的库而不是 openblas

我今天 运行 自己解决了这个问题,并向主线 Caffe 提交了拉取请求:

https://github.com/BVLC/caffe/pull/4247

对我来说,问题是 Caffe 正在寻找已弃用的 vecLib 框架(未发布 cblas.h)而不是新的 Accelerate 框架(已发布 cblas.h)。

转到 Makefile.config 并使用您的 openblas 所在的路径编辑以下行,在我的例子中版本是 0.2.18_2

一定要取消注释这些行:

BLAS_INCLUDE := /usr/local/Cellar/openblas/0.2.18_2/include
BLAS_LIB := /usr/local/Cellar/openblas/0.2.18_2/lib

取消注释 Makefile.config 中的这一行:

# 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

Makefile.config中:

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/local/opt/openblas/include/

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/local/opt/openblas/lib/

不确定这是否是最优雅的解决方案,但它确实有效。

对于我的 Caffe 安装,这是我的设置:

  • MacOS 10.12 Sierra,CPU_ONLY=ON,无 CUDA,无 Anaconda,具有 Python 接口
  • 通过 Make 编译(而不是 Cmake)official instructions here

我的 cblas.h 文件的目录(通过 Finder 搜索): /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Headers

将 cblas.h 路径添加到 ./caffe/Makefile.config:

# Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Headers/
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib

补充说明

另外对我来说,我有 OpenBlas。可能会影响您的情况。

# BLAS choice:
# atlas for ATLAS (default)
# mkl for MKL
# open for OpenBlas
BLAS := open

我还用 cblas.h 路径修改了 ./caffe/Makefile,但不确定是否有必要/有所不同。

else ifeq ($(BLAS), open)
    # OpenBLAS
    LIBRARIES += openblas
    BLAS_INCLUDE ?= /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Headers/

结果

原来的错误消失了:

但是下一个错误是(输出的尾端):

我fix/resolve/modify通过这个在Makefile.config:

# Homebrew puts openblas in a directory that is not on the standard search path
BLAS_INCLUDE := $(brew --prefix openblas)/include /usr/local/Cellar/openblas/0.3.3/include
BLAS_LIB := $(brew --prefix openblas)/lib /usr/local/Cellar/openblas/0.3.3/lib

我也在 Makefile 中解决了 -pthread 警告:

CXXFLAGS += -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11 #rm'd -pthread
LINKFLAGS += -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11 #rm'd -pthread

对于另一个 make cleancp Makefile.config.example Makefile.configmake all,这是输出的尾端,同样是输出的整个要点:

In file included from ./include/caffe/caffe.hpp:12:

所以看起来 make all 构建成功,假设这个 -L/lib 错误不会导致进一步的问题。注意:make allmake testmake runtest 运行 很好,只是产生了警告。 make pycaffe 然而产生了进一步的错误;稍后我可能 link 到我的解决方案。另外,是的,这个答案确实很长,超出了 OP 的要求,但希望我的回答可以在这个可怕的安装过程中帮助其他人。
