ubuntu16.04+pytorch--CPU版安装

ubuntu16.04+pytorch–CPU版安装

1、安装anaconda

anaconda下载地址
python对应anaconda版本
执行如下步骤安装

bash Anaconda3-2020.02-Linux-x86_64.sh
//安装完成执行如下,设置环境变量
gedit ~/.bashrc 
//添加环境变量
export PATH=/home/rikirobot/anaconda3/bin:$PATH

2、安装pytorch

我是官网哈哈哈!

conda install pytorch torchvision torchaudio cpuonly -c pytorch

运行报错

rikirobot@robot:~$ conda install pytorch torchvision torchaudio cpuonly -c pytorch
Fetching package metadata ...
........
Solving package specifications: 

PackageNotFoundError: Dependencies missing in current linux-64 channels: 
  - torchaudio -> pytorch 1.10.2 -> cudatoolkit >=11.1,<11.2
  - torchaudio -> pytorch 1.10.2 -> libuv >=1.40.0,<2.0a0
  - torchaudio -> pytorch 1.10.2 -> mkl >=2018
  - torchaudio -> pytorch 1.10.2 -> typing_extensions
  - torchaudio -> pytorch 1.10.2 -> dataclasses
  - torchaudio -> python_abi 3.9.* *_cp39
  - torchaudio -> librosa >=0.4.3
  - torchaudio -> sox

Close matches found; did you mean one of these?

    python_abi: python, ipython

(and similarly for the other packages)

找不到对应的包

解决:
1、使用conda,qinghua源去搜索包时出现了 packages missing 的错误,但并不代表这个包或者这个版本的包找不到,我们可以尝试用以下办法: anaconda search -t conda pytorch , 也可在后面加上包的版本号,去搜索:

2、anaconda show prigoyal/pytorch查看安装方法
