注意：如果你的Linux操作系统为32位的 请下载armv7结尾的.sh文件，但是Miniconda对armv7的支持版本已经很古老了，在创建虚拟环境Python3.7以上貌似都会出现问题，勉强支持到Python3.4版本左右，而且官方的作者对armv7结尾的.sh文件已经停更很久了，不建议安装使用，推荐树莓派安装64位的Linux。
Miniconda对armv7的支持参考：https://github.com/jjhelmus/berryconda
下载 miniconda
miniconda官方下载地址：https://repo.anaconda.com/miniconda/
miniconda清华镜像下载地址：https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/
因为我树莓派的Linux指令集为
aarch64
，所在miniconda官方仓库中选择了 Linux-aarch64 版本的，根据自己树莓派Linux的版本选择对应的版本，否则安装或在使用中会出错。

==>For changes to take effect, close and re-open your current shell. <==
If you’d prefer that conda’s base environment not be activated on startup,
set the auto_activate_base parameter to false:
conda config --set auto_activate_base false
Thank you for installing Miniconda3!
使用 cat 查看是否配置了Miniconda3 的环境变量，如果没有需要在.bashrc文件末尾自己手动添加
cat ~/.bashrc
根据 miniconda3 安装的路径，添加对应的环境变量
vim ~/.bashrc
更新配置文件
如果不更新配置文件会找不到 conda 命令
source ~/.bashrc
例如：
[email protected]:~$ conda -V
conda: command not found
查看安装的 conda 版本：
conda -V
(base)[email protected]:~/Software$ conda -V
conda 4.9.2
查看已安装依赖

创建虚拟环境
格式如下：
conda create -n [虚拟环境名称] python=[版本号]
示例：
激活刚创建的虚拟环境
格式如下：
source activate [虚拟环境名称]
示例：
source activate qqbot
查看虚拟环境中的Python版本
python --version
(qqbot) [email protected]:~/Software$ python --version
Python 3.8.11
安装依赖
卸载miniconda
找到miniconda3的文件夹，使用rm命令将它删除：
sudo rm -rf miniconda3/
然后，用vim命令进入.bashrc文件，将conda的语句用#注释掉
vim ~/.bashrc
最后，重新更新一下.bashrc文件就可以了。
source ~/.bashrc
遇到的问题
在安装 miniconda 4.10.1 遇到了以下问题，采用了降版本的方式解决了问题。
conda list Illegal instruction
注：目前大于4.9版本的miniconda不适配树莓派arm64架构操作系统，安装后无法正常使用！
