3、查看CUDA版本,是否安装成功

C:> nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Tue_Sep_15_19:12:04_Pacific_Daylight_Time_2020
Cuda compilation tools, release 11.1, V11.1.74
Build cuda_11.1.relgpu_drvr455TC455_06.29069683_0

4、安装Anaconda

conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/bioconda/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/menpo/
conda config --set show_channel_urls yes

5、安装pytouch

conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c conda-forge

或者

pip3 install torch==1.8.1+cu111 torchvision==0.9.1+cu111 torchaudio===0.8.1 -f https://download.pytorch.org/whl/torch_stable.html
3GB下载太慢了
解决方案:用户迅雷下载,然后安装本地下载文件的方式即可
10几倍的差距,几分钟就好了
pip install e:/torch-1.8.1+cu111-cp37-cp37m-win_amd64.whl
$ python3
Python 3.8.5 (default, Sep  4 2020, 07:30:14)

>>> import torch 
>>> x = torch.empty(5, 3) 
>>> print(x) 
tensor([[1.0966e+14, 4.5883e-41, 1.0966e+14],
        [4.5883e-41, 1.0966e+14, 4.5883e-41],
        [1.0968e+14, 4.5883e-41, 1.0966e+14],
        [4.5883e-41, 1.0968e+14, 4.5883e-41],
        [1.0968e+14, 4.5883e-41, 1.0968e+14]])
