uname -a

pi@raspbian:~/Software$ uname -a
Linux raspbian 5.4.83-OPENFANS+20210102-v8 #1 SMP Sat Jan 2 21:52:54 CST 2021 aarch64 GNU/Linux

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。

如果需要下载 Miniconda3-python3.7的安装包,则执行以下这条

wget https://repo.continuum.io/miniconda/Miniconda3-py37_4.9.2-Linux-aarch64.sh

如果需要下载 Miniconda3-python3.9的安装包,则执行以下这条

wget https://repo.continuum.io/miniconda/Miniconda3-py39_4.9.2-Linux-aarch64.sh

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
export PATH=/home/pi/miniconda3/bin:$PATH

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:

pi@raspbian:~$ conda -V
conda: command not found

查看安装的 conda 版本:

conda -V

(base)pi@raspbian:~/Software$ conda -V
conda 4.9.2

查看已安装依赖

conda list

(base) pi@raspbian:~/Software$ conda list

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:

conda create -n qqbot python=3.8

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) pi@raspbian:~/Software$ python --version
Python 3.8.11

安装依赖

conda install [依赖名称]
pip install [依赖名称]

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!

参考:https://stackoverflow.com/questions/68099000/conda-init-illegal-instruction-core-dumped
