Python包管理工具PIP/Conda/Mamba

pip

先安装python，才能使用pip安装python的软件

后面就很简单了

conda安装【不过需要VC++环境自己注意下吧】

 当然也可以miniconda

mamba也差不多

左边是conda，右边是mamba，几乎完全一样，所以用过conda，mamba几乎不用学习就可使用。

创建Python环境也是一样的

mamba create --name python3.5 python=3.5 #完美替代conda

激活推出如下：

conda activate python3.5 #激活python3.5环境
conda deactivate #退出python3.5环境

其实快不快主要看你的配置：多引用国内的源就可以了：

2. pip换源

pip国内的一些镜像:
阿里云 http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban) http://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/

临时使用某个源安装版本:
pip install -i https://pypi.douban.com/simple torch==1.5.0

感兴趣就都尝试一下，两鸟在林，不如一鸟在手。
