问题： The NVIDIA driver on your system is too old (found version 9000). Please update your GPU driver by downloading and installing a new version from the URL: http://www.nvidia.com/Download/index.aspx Alternatively, go to: https://pytorch.org to install a PyTorch version that has been compiled with your version of the CUDA driver.
问题是说cuda太旧了，或者说你的torch太新了，不匹配。所以建议重装合适的torch 进入python查看torch版本
>>> import torch >>> torch.__version__ '1.6.0'cat /usr/local/cuda/version.txt 查看cuda版本
关于不同版本的pytorch和CUDA版本的对应关系： pytorch官网：https://pytorch.org/get-started/previous-versions/ 页面有命令，直接复制，真的有够人性化
