原因pytorch 好像会自带一套cuda工具 A-100 这张卡，好像只支持cuda 11.0 以上的版本和pytouch 自带的cuda 有冲突

官网链接

https://pytorch.org/get-started/previous-versions/

卸载旧的pytorch
conda uninstall pytorch
conda uninstall libtorch
pip uninstall torch
安装新的pytorch
#安装 CUDA 11.0
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch

#安装 pytorch_lightning
python -m  pip install pytorch_lightning

# 更新 transformers 到最新版本 
python -m pip install transformers

# 更新 torch-sparse 到最新版本 很慢
python -m pip install torch-sparse

如果运行失败

https://pytorch-geometric.com/whl/torch-1.7.1%2Bcu110.html 从这里下载 对应python cuda的 插件

检查命令

import torch

print(torch.__version__)
print(torch.version.cuda)
print(torch.cuda.is_available())

代码更改
