Question

我的操作系统是CentOS 7，我想安装PyTorch，所以我做了以下事情：

(pt_gpu) [martin@A08-R32-I196-3-FZ2LTP2 mlm]$ conda -V
conda 4.6.2

(pt_gpu) [martin@A08-R32-I196-3-FZ2LTP2 mlm]$ conda install -c anaconda pytorch-gpu

奇怪的是，安装消息显示它正在安装非常旧的PyTorch版本：

Solving environment: done

## Package Plan ##

  environment location: /home/martin/anaconda3/envs/pt_gpu

  added / updated specs:
    - pytorch-gpu


The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    ca-certificates-2018.12.5  |                0         123 KB  anaconda
    certifi-2018.11.29         |           py36_0         146 KB  anaconda
    pytorch-gpu-0.1.12         |           py36_0        16.8 MB  anaconda
    ------------------------------------------------------------
                                           Total:        17.0 MB

The following packages will be UPDATED:

  openssl              pkgs/main::openssl-1.1.1a-h7b6447c_0 --> anaconda::openssl-1.1.1-h7b6447c_0

The following packages will be SUPERSEDED by a higher-priority channel:

  ca-certificates                                 pkgs/main --> anaconda
  certifi                                         pkgs/main --> anaconda
  mkl                    pkgs/main::mkl-2017.0.4-h4c4d0af_0 --> anaconda::mkl-2017.0.1-0
  pytorch-gpu                                     pkgs/free --> anaconda

要验证安装了什么，我做了：

(pt_gpu) [martin@A08-R32-I196-3-FZ2LTP2 mlm]$ python -c "import torch; print(torch.__version__)"
0.1.12

那是为什么？

Answer 1

根据他们的官方网站（https://pytorch.org），他们安装了名为pytorch而不是pytorch-gpu的软件包。

conda install pytorch torchvision -c pytorch

为什么我不能安装新版本的Pytorch？
