矩池云上安装 NVCaffe 教程

使用的是 P100，cuda11.1base 镜像

创建虚拟环境

conda create -n py36 python=3.6
conda deactivate
conda activate py36

安装依赖包

apt update
apt-get install libopencv-dev libopenblas-dev libopenblas-base libhdf5-dev protobuf-compiler libgoogle-glog-dev libgflags-dev libprotobuf-dev libboost-dev libleveldb-dev liblmdb-dev libturbojpeg0-dev  libboost-filesystem-dev libboost-system-dev libboost-thread-dev libboost-regex-dev libsnappy-dev

下载 NVIDIA caffe

cd /home/

# 官方链接wget https://github.com/NVIDIA/caffe/archive/refs/tags/v0.17.4.tar.gz
我这里用了镜像来下载
wget https://download.fastgit.org/NVIDIA/caffe/archive/refs/tags/v0.17.4.tar.gz

tar -xvf v0.17.4.tar.gz
cd caffe-0.17.4

for req in $(cat python/requirements.txt); do pip install $req; done
pip install --upgrade google-api-python-client

cp Makefile.config.example Makefile.config

修改 Makefile.config

想自己找到上面修改的路径，可以使用下面的命令查找

python -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())"
python -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR'))"

find /root/miniconda3/envs/py36/lib/ -name numpy

设置环境变量

export PYTHONPATH=/home/caffe-0.17.4/python/:$PYTHONPATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/root/miniconda3/envs/py36/lib

开始编译

make clean
make all -j12
make pycaffe -j12

使用 python 环境测试

python

import caffe
caffe.set_mode_gpu()
caffe.__version__

使用官方 examples 测试

#!/usr/bin/env sh
# This scripts downloads the mnist data and unzips it.

DIR="$( cd "$(dirname "$0")" ; pwd -P )"
cd $DIR
