使用Anaconda虚拟环境编译caffe-gpu pycaffe

1. 前提:

安装前服务器情况,已经安装好了:

1. CUDNN=7.3.0
   

2. CUDA=10.0.130
   

3. Opencv 2.4.13

   

相应命令为:

cuda 版本
cat /usr/local/cuda/version.txt
cudnn 版本
cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2
opencv版本
pkg-config opencv --modversion

2. 准备caffe, python环境

• 从https://github.com/BVLC/caffe下载caffe, 用unzip命令解压.
• python我使用的是Anaconda虚拟环境, 最后附上environment_caffe_27.yml文件, 如果需要可以直接使用下面的命令安装,或者手动安装.

```
conda env create -f environment_caffe_27.yml
```
environment_caffe_27.yml文件内容如下,复制重命名即可:

关于环境需要说明一下:

1. 在下载的caffe-master中, 有requirements.txt, 也可以先新建虚拟环境, 然后激活后使用pip install -r python/requirements.txt 安装包.
2. protobuf版本在requirements.txt中值写了最小值,实测最新版的protobuf不知此, 建议安装3.2版本, 即使用conda install protobuf=3.2
3. requirements.txt中,要求python-dateutil>=1.4,<2, 但是这个版本太老了找不到, 我安装的了2.8版本,实测编译通过,调用正常.

3. 复制修改Makefileconfig文件

cp Makefile.config.example Makefile.config
`vim Makefileconfig.config', 附上我的文件内容，　可根据实际情况修改：

## Refer to http://caffe.berkeleyvision.org/installation.html

Q ?= @

4. 虚拟环境添加到环境变量，不然报错（亲自踩坑，但是不解）

参考链接找不到了, 但是店家内容如下:
export PATH="/opt/anaconda/envs/bin:$PATH"

5. 开始编译

make all –j8
make test –j8
make runtest –j8
make pycaffe  -j8

详细参考博文：　Ubuntu16.04 14.04安装配置Caffe(GPU版), 解释很详细，如果用我的python环境,不需要按照博文再安装其他的包,直接编译即可.

6. 测试

source activate caffe_27, 其中caffe_27是我的虚拟环境名称, 然后输入python:
再输入import caffe 导入成功~,,,(折腾了一天,心累)
