安装步骤
首先从github
上面拷贝下来caffe
项目:
git clone https://github.com/BVLC/caffe.git
cd caffe
安装caffe
版的SSD
拷贝步骤为:
git clone https://github.com/weiliu89/caffe.git
cd caffe
git checkout ssd
然后将caffe
主目录下面的Makefile.config.example
拷贝更名为Makefile.config
,打开操作:
cp Makefile.config.example Makefile.config
gedit Makefile.config
将其中的:
#USE_CUDNN := 1
#WITH_PYTHON_LAYER := 1
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
分别更改为:
USE_CUDNN := 1
WITH_PYTHON_LAYER := 1
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial
打开 Makefile
文件:
gedit makefile
将其中的:
NVCCFLAGS += -ccbin=$(CXX) -Xcompiler-fPIC $(COMMON_FLAGS)
更改为:
NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)
打开/usr/local/cuda/include/crt/host_config.h
文件:
sudo gedit /usr/local/cuda/include/crt/host_config.h
将其中的:
#error-- unsupported GNU version! gcc versions later than 4.9 are not supported!
更改为:
//#error-- unsupported GNU version! gcc versions later than 4.9 are not supported!
下面就是编译caffe
并测试:
make clean -j8
make all -j8
make runtest -j8
最后输出PASS
说明测试成功。
配置环境变量:
vim ~/.bashrc
在文件末尾写入caffe-pathon
的安装路径:
export PYTHONPATH=~/caffe/python:$PYTHONPATH
上述语句中的~
表示caffe所在的根目录。
是环境变量生效:
source ~/.bashrc
然后执行:
make pycaffe
cuda9编译问题
错误:
NVCC src/caffe/layers/bnll_layer.cu
nvcc fatal : Unsupported gpu architecture 'compute_20'
Makefile:594: recipe for target '.build_release/cuda/src/caffe/layers/bnll_layer.o' failed
make: *** [.build_release/cuda/src/caffe/layers/bnll_layer.o] Error 1
make: *** Waiting for unfinished jobs....
原因
cuda9不支持‘ compute-20 ’
解决方案
修改Makefile.config
文件中CUDA_ARCH
设置,将
# CUDA architecture setting: going with all of them.
# For CUDA < 6.0, comment the *_50 through *_61 lines for compatibility.
# For CUDA < 8.0, comment the *_60 and *_61 lines for compatibility.
# For CUDA >= 9.0, comment the *_20 and *_21 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_35,code=sm_35 \
-gencode arch=compute_50,code=sm_50 \
-gencode arch=compute_52,code=sm_52 \
-gencode arch=compute_60,code=sm_60 \
-gencode arch=compute_61,code=sm_61 \
-gencode arch=compute_61,code=compute_61
中的
-gencode arch=compute_20,code=sm_20 \
-gencode arch=compute_20,code=sm_21 \
删除即可重新编译。
