#31 环境安装有疑问

hi @xiaobaistudy 你还需要运行以下命令：`pip install d2l torch`，复制粘贴到 Anaconda 中就可以开始深度学习啦😀

vim ~/.condarc

default_channels:
  - https://mirror.sjtu.edu.cn/anaconda/pkgs/r
  - https://mirror.sjtu.edu.cn/anaconda/pkgs/main
custom_channels:
  conda-forge: https://mirror.sjtu.edu.cn/anaconda/cloud/
  pytorch: https://mirror.sjtu.edu.cn/anaconda/cloud/
channels:
  - defaults

conda create -n d2l python=3.9

conda activate d2l

pip config set global.index-url https://mirror.sjtu.edu.cn/pypi/web/simple

pip install torch==1.12.0
pip install torchvision==0.13.0

pip install d2l

git clone https://openi.pcl.ac.cn/Datawhale/d2l

(sudo) apt install git    #ubuntu系统
(sudo) yum install git  #centos系统

pip install jupyterlab

jupyter lab passwd

jupyter lab --ip 0.0.0.0 --allow-root

### 更换conda源 ```bash vim ~/.condarc ``` 内容如下： ``` default_channels: - https://mirror.sjtu.edu.cn/anaconda/pkgs/r - https://mirror.sjtu.edu.cn/anaconda/pkgs/main custom_channels: conda-forge: https://mirror.sjtu.edu.cn/anaconda/cloud/ pytorch: https://mirror.sjtu.edu.cn/anaconda/cloud/ channels: - defaults ``` ### 创建学习环境 ```bash conda create -n d2l python=3.9 ``` ### 激活环境 ```bash conda activate d2l ``` ### 变更pip源头 ```bash pip config set global.index-url https://mirror.sjtu.edu.cn/pypi/web/simple ``` ### 安装必要的包 **安装torch** ```bash pip install torch==1.12.0 pip install torchvision==0.13.0 ``` **安装d2l包** ```bash pip install d2l ``` ### 下载代码仓 ```bash git clone https://openi.pcl.ac.cn/Datawhale/d2l ``` 注：如果没有git工具安装命令如下 ```bash (sudo) apt install git #ubuntu系统 (sudo) yum install git #centos系统 ``` ### 安装jupyter lab 个人比较喜欢使用juypter lab进行时间，如果喜欢使用notebook的话可以不执行这一步 **安装** ```bash pip install jupyterlab ``` **设置密码** ```bash jupyter lab passwd ``` ### 启动juypterlab ```bash jupyter lab --ip 0.0.0.0 --allow-root ``` 至此环境准备工作全部完成
