Question

我正在Jetson-TK1板上建造caffe。该板运行Ubuntu Linux 32bit。我的Makefile.config如下

## Refer to http://caffe.berkeleyvision.org/installation.html
# Contributions simplifying and improving our build system are welcome!

# cuDNN acceleration switch (uncomment to build with cuDNN).
#USE_CUDNN := 1

# CPU-only switch (uncomment to build without GPU support).
#CPU_ONLY := 1

# To customize your choice of compiler, uncomment and set the following.
# N.B. the default for Linux is g++ and the default for OSX is clang++
#CUSTOM_CXX := g++

# CUDA directory contains bin/ and lib/ directories that we need.
CUDA_DIR := /usr/local/cuda-6.5
# On Ubuntu 14.04, if cuda tools are installed via
# "sudo apt-get install nvidia-cuda-toolkit" then use this instead:
# CUDA_DIR := /usr

# CUDA architecture setting: going with all of them.
# For CUDA < 6.0, comment the *_50 lines for compatibility.
CUDA_ARCH := -gencode arch=compute_20,code=sm_20 \
        -gencode arch=compute_20,code=sm_21 \
        -gencode arch=compute_30,code=sm_30 \

        -gencode arch=compute_50,code=sm_50 \
        -gencode arch=compute_50,code=compute_50

# BLAS choice:
# atlas for ATLAS (default)
# mkl for MKL
# open for OpenBlas
BLAS := atlas
# Custom (MKL/ATLAS/OpenBLAS) include and lib directories.
# Leave commented to accept the defaults for your choice of BLAS
# (which should work)!

BLAS_LIB := /usr/lib

# 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

# This is required only if you will compile the matlab interface.
# MATLAB directory should contain the mex binary in /bin.
# MATLAB_DIR := /usr/local
# MATLAB_DIR := /Applications/MATLAB_R2012b.app

# NOTE: this is required only if you will compile the python interface.
# We need to be able to find Python.h and numpy/arrayobject.h.

PYTHON_INCLUDE := /usr/include/python2.7 \

        # $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include \

# We need to be able to find libpythonX.X.so or .dylib.
PYTHON_LIB := /usr/lib
# PYTHON_LIB := $(ANACONDA_HOME)/lib

# Homebrew installs numpy in a non standard path (keg only)
# PYTHON_INCLUDE += $(dir $(shell python -c 'import numpy.core; print(numpy.core.__file__)'))/include
# PYTHON_LIB += $(shell brew --prefix numpy)/lib

# Uncomment to support layers written in Python (will link against Python libs)
# WITH_PYTHON_LAYER := 1

# Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/local/hdf5/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/local/hdf5/lib


# If Homebrew is installed at a non standard location (for example your home directory) and you use it for general dependencies
# INCLUDE_DIRS += $(shell brew --prefix)/include

# Uncomment to use `pkg-config` to specify OpenCV library paths.
# (Usually not necessary -- OpenCV libraries are normally installed in one of the above $LIBRARY_DIRS.)
# USE_PKG_CONFIG := 1

BUILD_DIR := build
DISTRIBUTE_DIR := distribute

# Uncomment for debugging. Does not work on OSX due to https://github.com/BVLC/caffe/issues/171

# The ID of the GPU that 'make runtest' will use to run unit tests.

我可以make all成功。运行make test时出现错误。错误是

我使用的是CUDA-6.5。

这个版本可能有什么问题？

编辑1： @Klaus Prinoth提到的link是有用的。现在我可以建立。我还可以测试build/tools/caffe time --model=models/bvlc_alexnet/deploy.prototxt --gpu=0的CPU和GPU。但当我make -j 8 runtest时，我收到了Check Failed的消息。我不确定是什么问题。消息是

该消息是什么意思？

Answer 1

我按照以下步骤解决了问题。这些是link中提到的步骤。

（1）需要确保安装了所有依赖项。他们是

    sudo apt-get install \
    libprotobuf-dev protobuf-compiler gfortran \
    libboost-dev cmake libleveldb-dev libsnappy-dev \
    libboost-thread-dev libboost-system-dev \
    libatlas-base-dev libhdf5-serial-dev libgflags-dev \
    libgoogle-glog-dev liblmdb-dev gcc-4.7 g++-4.7

由于我不使用Python，因此我跳过了Python接口所需的步骤。

（2）获取咖啡源

sudo apt-get install git
git clone https://github.com/BVLC/caffe.git
cd caffe
cp Makefile.config.example Makefile.config

（3）需要在make -j 8 runtest之前将src / caffe / util / db.cpp中的1099511627776更改为536870912，否则将导致MDB_MAP_FULL error in runtest。我的Makefile.config显示在原始帖子中。那你就准备好了

make -j 8 all
make -j 8 test
make -j 8 runtest

可以使用

测试CPU和GPU处理的性能差异

对于GPU：＆＃34; run build/tools/caffe time --model=models/bvlc_alexnet/deploy.prototxt --gpu=0＆＃34;

对于CPU：＆＃34; run build/tools/caffe time --model=models/bvlc_alexnet/deploy.prototxt＆＃34; 感谢@Klaus Prinoth给我链接。
