第1步：安装Anaconda
-
说明：使用paddlepaddle需要先安装python环境，这里我们选择python集成环境Anaconda工具包
- Anaconda是1个常用的python包管理程序；
- 安装完Anaconda后，可以安装python环境，以及numpy等所需的工具包环境；
下载Anaconda：
-
下载地址：https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/?C=M&O=D
image.png -
选择适合您操作系统的版本
- 可在终端输入uname -m查询系统所用的指令集
[root@test-web2 /]# uname -m
x86_64
- 本地下载，再将安装包传到linux服务器上
https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2023.07-2-Linux-x86_64.sh- 若您要下载其他版本，需要将最后1个/后的文件名改成您希望下载的版本
- 安装Anaconda：
[root@test-web2 ~]# chmod +x Anaconda3-2023.07-2-Linux-x86_64.sh
[root@test-web2 ~]# ll Anaconda3-2023.07-2-Linux-x86_64.sh
-rwxr-xr-x 1 root root 1064920017 9月 25 11:17 Anaconda3-2023.07-2-Linux-x86_64.sh
sh Anaconda3-2023.07-2-Linux-x86_64.sh
若您下载的是其它版本，则将该命令的文件名替换为您下载的文件名
按照安装提示安装即可
查看许可时可输入q来退出

将conda加入环境变量
- 加入环境变量是为了让系统能识别conda命令，若您在安装时已将conda加入环境变量path，则可跳过本步
- 在终端中打开/etc/profile：
# 在终端中输入以下命令：
vim /etc/profile
... ...
export PATH="/root/anaconda3/bin:$PATH"
- 验证是否能识别conda命令：
source /etc/profile
conda info --envs #若能显示当前有base环境，则conda已加入环境变量

第2步：创建conda环境
- 创建新的conda环境
# 在命令行输入以下命令，创建名为paddle_env的环境
# 此处为加速下载，使用清华源
conda create --name paddle_env python=3.10 --channel https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
image.png
image.png
- 该命令会创建1个名为paddle_env、python版本为3.10的可执行环境，根据网络状态，需要花费一段时间
- 之后命令行中会输出提示信息，输入y并回车继续安装
激活刚创建的conda环境，在命令行中输入以下命令：
# 激活paddle_env环境
conda activate paddle_env
报错：
# conda activate paddle_env
usage: conda [-h] [--no-plugins] [-V] COMMAND ...
conda: error: argument COMMAND: invalid choice: 'activate' (choose from 'clean', 'compare', 'config', 'create', 'info', 'init', 'install', 'list', 'notices', 'package', 'remove', 'uninstall', 'rename', 'run', 'search', 'update', 'upgrade', 'build', 'convert', 'debug', 'develop', 'doctor', 'index', 'inspect', 'metapackage', 'render', 'skeleton', 'pack', 'verify', 'token', 'repo', 'env', 'server', 'content-trust')
解决方法
查询当前环境位置，试用 source activate 进行激活就可以解决问题。
#查询环境位置
conda info | grep -i 'base environment'
base environment : /root/anaconda3 (writable)
# /root/anaconda3 是你自己的输出结果
source /root/anaconda3/etc/profile.d/conda.sh
#激活sh
conda activate paddle_env
#可以运行了
conda deactivate
#退出虚拟环境
conda env remove -n paddle_env
#删除虚拟环境paddle_env
image.png
- 以上anaconda环境和python环境安装完毕
第3步：安装程序所需要库
- 使用pip命令在刚激活的环境中安装paddle：
# 在命令行中输入以下命令：
# 默认安装CPU版本，安装paddle时建议使用百度源
pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple
(paddle_env) [root@test-web2 ~]# pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple

ImportError: libssl.so.1.1: cannot open shared object file: No such file or directory
解决办法：
Centos7 默认提供的 openssl 版本是 1.0.2 的，如果过低的话就会报错 libssl.so.1.1: cannot open shared object file: No such file or directory，这是由于 openssl 库的位置不正确或未安装 1.1 以上版本的问题；
想要升级 openssl 版本则需要手动进行编译，报错解决方式很简单，安装正确即可
#下载 openssl
wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz
或者
wget https://mirrors.cloud.tencent.com/openssl/source/openssl-1.1.1g.tar.gz
#编译 openssl
tar -xvf openssl-1.1.1g.tar.gz
cd openssl-1.1.1g
./config shared --openssldir=/usr/local/openssl --prefix=/usr/local/openssl
make && make install
编译完成后，使用 openssl version 来查看一下当前 openssl 版本号时，你会发现还是 1.0.2，所以这里需要做一些额外的配置工作
#配置
mv /usr/bin/openssl /usr/bin/openssl.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
