服务器上ssh实现
写在前面:这只是我在服务器上的环境实现的,仅供参考。要根据自己系统的环境做出修改。
==github源码(https://github.com/mahyarnajibi/SSH)==
**实现参考(https://blog.csdn.net/qq_14845119/article/details/79105360)**
(https://blog.csdn.net/zziahgf/article/details/72900948)
初始工作:安装cuda和cudnn还有nccl
因为服务器上装好了cuda和cudnn,我选择了cuda9.0和cudnn7.0。所以直接安装nccl
从github获取并安装
git clone https://github.com/NVIDIA/nccl.git
cd nccl
make clean && make PREFIX=$NCCL_ROOT_DIR install
$NCCL_ROOT_DIR是自己安装的路径:比如我的路径是 /home/lzm/data/nccl/install则为:
make clean && make PREFIX=/home/lzm/data/nccl/install install
等nccl安装完成
安装caffe-ssh
1、所有都在conda建立的python虚拟环境下进行如:
conda create -n caffetest(虚拟) python=2.7(不是2.7貌似会报错) anaconda
conda activate caffetest
2、从github获取源码:
git clone --recursive https://github.com/mahyarnajibi/SSH.git
3、进入目录SSH安装需要的python模块:
cd SSH
pip install -r requirements.txt
4、建立临时环境变量env
(1)把nccl和conda环境写入env文件:
dlm-conda activate caffetest
export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/include
export C_INCLUDE_PATH=$C_INCLUDE_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/include
export LIBRARY_PATH=$LIBRARY_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/lib
(2)激活环境变量:
source ./env
5、配置文件将Makefile.config.example拷贝一份成配置文件:
cd caffe-ssh
cp Makefile.config.example Makefile.config
修改Makefile.config
(1)改成自己cuda的目录:
CUDA_DIR := /usr/local/cuda
改成
CUDA_DIR := /usr/local/nvidia/cuda/9.0
(2)去掉的注释:
#OPENCV_VERSION := 3
改成
OPENCV_VERSION := 3
(3)修改环境路径
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
改为
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/hdf5/serial/
6、安装缺少模块
conda install -c conda-forge readline=6.2
conda install libgcc
7、编译
make all -j32
8、编译pycaffe生成接口
make pycaffe
9、在lib中编译运行setup.py
cd ../lib/
make
10、用scripts中的脚本下载模型
cd ..
bash scripts/download_ssh_model.sh
bash scripts/ download_imgnet_model.sh
11、运行模型演示
python demo.py
结果如下:
可能出现的问题
(1)
问题:
Unsupported gpu architecture 'compute_20'
解决方案:
https://askubuntu.com/questions/960238/nvcc-fatal-unsupported-gpu-architecture-compute-20
即去掉Makefile.config 中两行:
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_50,code=compute_50
改为:
CUDA_ARCH := -gencode arch=compute_50,code=sm_50
-gencode arch=compute_52,code=sm_52
-gencode arch=compute_60,code=sm_60
-gencode arch=compute_62,code=sm_62
-gencode arch=compute_61,code=compute_61
(2)
问题:
awk: symbol lookup error: /home/lzm/.conda/envs/lzm2/lib/libreadline.so.6: undefined symbol: PC
解决方案:
https://github.com/conda-forge/rpy2-feedstock/issues/1
https://github.com/bioconda/bioconda-recipes/issues/5350
即 run
conda install -c conda-forge readline = 6.2
(3)
问题:
./include/caffe/util/hdf5.hpp:6:18: fatal error: hdf5.h: no such file or directory
解决方案:
https://github.com/BVLC/caffe/issues/2690
https://github.com/NVIDIA/DIGITS/issues/156
即Makefile.config 拿两行改掉:
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
改为
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/
(4)
问题:
./include/caffe/util/nccl.hpp:5:18: fatal error: nccl.h: No such file or directory
解决方案:
新建文件为env
将服务器已经安装的nccl路径配置到env:
export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/include
export C_INCLUDE_PATH=$C_INCLUDE_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/include
export LIBRARY_PATH=$LIBRARY_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/lzm/data/caffe/caffe1.0_nccl/nccl/install/lib
每次要用的时候都激活环境:
source ./env
(5)
问题:
.build_release/lib/libcaffe.so: undefined reference to `cv::imdecode
解决方案:https://github.com/BVLC/caffe/issues/4621
把Makefile.config 中 OPENCV_VERSION = 3的注释去掉即可
(6)
问题:
/caffe/bin/../lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by caffe-ssh/python/caffe/_caffe.so)
解决方案:https://github.com/BVLC/caffe/issues/4953
conda install libgcc
PS:以上问题也是自己经过很久的搜索排查得出来的,不要怕麻烦,要善于搜索引擎,一切水到渠成
