1. 下载anaconda版本：current version: 4.10.1
2. 打开anaconda prompt
3. 按顺序输入以下命令

conda create -n pytorch python=3.6

conda activate pytorch

# CUDA 9.2
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=9.2 -c pytorch

# CUDA 10.1
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=10.1 -c pytorch

# CUDA 10.2
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=10.2 -c pytorch

# CUDA 11.0
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch

# CPU Only
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cpuonly -c pytorch

安装检测

python
import torch
torch.cuda.is_available()

显示True即为安装成功

## 如果出现下载安装问题

Loading channels: failed
 
CondaHTTPError: HTTP 404 NOT FOUND for url 
Elapsed: 00:00.084698
 
The remote server could not find the noarch directory for the
requested channel with url: https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
 
As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json` is
empty. please request that the channel administrator create
`noarch/repodata.json` and associated `noarch/repodata.json.bz2` files.
$ mkdir noarch
$ echo '{}' > noarch/repodata.json
$ bzip2 -k noarch/repodata.json
 
You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current state.
Further configuration help can be found at .

输入以下命令：

conda config --remove-key channels
