Conda

Anaconda & Miniconda

Anaconda is conda with some frequently used(although I disagree) preinstalled packages
Miniconda is conda with only base modules, and we have to install every dependencies we need

I prefer Miniconda

Installing

Download

1	>>> wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

Install

1	>>> ./Miniconda3-latest-Linux-x86_64.sh

初始化可以选yes（会修改环境变量）

1
2
3

Do you wish the installer to initialize Miniconda3
by running conda init? [yes|no]
[no] >>> yes

重启后即可

Using

Create Environment

1	>>> conda create --name env-for-torch python=3.9
