使用git、wget方式下载：
失败
从官网下载下来模型并上传，讲代码中模型导入的路径改为本地路径
下载过程可以参考该博客。
不知道为啥直接变成了路径接上，不过不重要，最后也不知道怎么捣鼓的反正就是接上了，成功导入，出现另一个错误：
下午再解决，累了
RuntimeError: The NVIDIA driver on your system is too old (found version 10010). 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.
好像是不能直接下载最新版的pytorch，跟cuda的版本对不上（好像是），所以去找一下怎么下载特定版本的pytorch，另：昨天好像手滑把另一个配好的cuda环境的pytorch搞没了，记得找到怎么下载1.1.0版本的pytorch后，重新去那个版本里再下一个。
bart要求的pytorch版本因该是>=1.6.0的。
具体cuda和pytorch、torchvision对应版本的下载语句如下网页所示：
https://pytorch.org/get-started/previous-versions/#conda-3
查看显卡内存：
nvidia-smi
换卡3试试
指定使用哪块显卡的语句：
os.environ['CUDA_VISIBLE_DEVICES']='3'
但是依旧报错，考虑是所有卡的空间都不太够了
因为这份代码已经添加了去掉梯度的语句，所以不可再添加去掉梯度的语句了，添加梯度的博客：
https://www.cnblogs.com/dyc99/p/12664126.html
https://blog.csdn.net/weixin_43760844/article/details/113462431
明早等卡没人用了再说。
有卡了，还是报错，先看论文吧
