wsl安装torch_geometric

1. 在官网选择需要的版本

2. 选择安装途径，选择runfile

3. 执行第一行，会下载一个文件到目录下

4. 需要降低C++的版本，否则

   执行sudo sh cuda_11.1.0_455.23.05_linux.run,会出现

   

   查看对应的文件，会有

   

   可以加上override参数之后，继续安装

5. 降低gcc版本，但是会出现错误

   E: Package ‘g+±7’ has no installation candidate

   

6. 解决E: Package ‘g+±7’ has no installation candidate错误，需要更换ubuntun 20.04的镜像源

   # 修改 apt-get 源的配置文件
   sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak #备份
   sudo vim /etc/apt/sources.list #修改deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse# deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
   # deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse#最后执行
   sudo apt-get update
   

   如果删除了原本的镜像源内容，使用nvcc -V命令，发现没有了，安装的话也会失败

   The following packages have unmet dependencies:  nvidia-cuda-toolkit :
   Depends: nvidia-cuda-dev (= 10.1.243-3) but it is not going to be
   installed E: Unable to correct problems, you have held broken
   packages.
   Running `sudo apt install nvidia-cuda-dev` yields:The following packages have unmet dependencies:  nvidia-cuda-dev :
   Depends: libcublas10 (= 10.1.243-3) but 10.2.2.214-1 is to be
   installedRecommends: libvdpau-dev but it is not going to be installedRecommends: libnvcuvid1 but it is not installable E: Unable to correct problems, you have held broken packages.
   

   原因更改了 /etc/apt/sources.list can’t install nvidia-driver-toolkit on Ubuntu 20.04 LTS - needs uninstallable package - Ask Ubuntu

   方法：在/etc/apt/sources.list中添加

   deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiversedeb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiversedeb http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
   

   镜像源更改之后，执行

   sudo apt-cache policy
   sudo apt-get --purge remove "*cublas*" "cuda*" "*nvidia*"
   sudo apt-get clean
   sudo apt-get autoremove
   sudo apt-get update
   sudo apt-get upgrade
   sudo apt-get install nvidia-cuda-toolkit
   

   再次执行安装nvcc的命令

7. 降低g++版本之后，可以正常执行 sudo sh cuda_11.1.0_455.23.05_linux.run, 前面有X的是选中要安装的，[ ]是不安装的

8. 安装完成后显示

   

9. 正常安装cuda 11.1了，虽然nvidia-smi显示和nvcc -V显示的版本不同，以nvcc -V为主

   

10. /usr/local目录下有了 cuda目录

    

11. 更新可执行文件路径,在 vim ~/.bashrc中加入,如果不在 ~/.bashrc中加入的话，下次启动还是找不到cuda

    export PATH=/usr/local/cuda-11.1/bin${PATH:+:${PATH}}
    

12. 更新动态链接库路径，在 vim ~/.bashrc中加入

    export LD_LIBRARY_PATH=/usr/local/cuda-11.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
    

13. 安装1.8.1版本的torch https://pytorch.org/get-started/previous-versions/

    # CUDA 11.1
    pip install torch==1.8.1+cu111 torchvision==0.9.1+cu111 torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html
    

14. 然后安装torch-geometric, 根据torch和cuda版本选择，

    

15. 安装顺序为 torch-scatter2.0.8，torch-sparse0.6.12，torch-cluster1.5.9，torch-spline-conv1.2.1，torch-geometric==1.7.0，我的python版本为3.6， wsl(linux)
