查看安装docker的包

[root@host20 ~]#  rpm -qa | grep docker 
docker-1.13.1-208.git7d71120.el7_9.x86_64

docker-client-1.13.1-208.git7d71120.el7_9.x86_64

删除docker低版本包

[root@host20 ~]#  yum remove docker-common-1.13.1-208.git7d71120.el7_9.x86_64  docker-client-1.13.1-208.git7d71120.el7_9.x86_64 docker-1.13.1-208.git7d71120.el7_9.x86_64

================================================================================

To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:

    dockerd-rootless-setuptool.sh install

Visit https://docs.docker/go/rootless/ to learn about rootless mode.


To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent
         to root access on the host. Refer to the 'Docker daemon attack surface'
         documentation for details: https://docs.docker/go/attack-surface/

[root@host20 ~]# 

示例：pandas 是基于NumPy 的一种工具，该工具是为了解决数据分析任务而创建的。

二、查看docker版本并启动docker

1.引入库

[root@host20 ~]# docker --version
Docker version 20.10.8, build 3967b7d
[root@host20 ~]# systemctl start docker
[root@host20 ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@host20 ~]# 

2. 执行以下命令

[root@host20 ~]# yum install -y yum-utils >   device-mapper-persistent-data >   lvm2
[root@host20 ~]#  systemctl enable docker
[root@host20 ~]# 

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import warnings
warnings.filterwarnings('ignore')
import  ssl
ssl._create_default_https_context = ssl._create_unverified_context

2.读入数据

代码如下（示例）：

data = pd.read_csv(
    'https://labfile.oss.aliyuncs/courses/1283/adult.data.csv')
print(data.head())

该处使用的url网络请求的数据。

总结

提示：这里对文章进行总结：
例如：以上就是今天要讲的内容，本文仅仅简单介绍了pandas的使用，而pandas提供了大量能使我们快速便捷地处理数据的函数和方法。
