随便找个代码块执行下面的命令

%pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchtext==0.14.1 torchaudio==0.13.1 torchdata==0.5.1 --extra-index-url https://download.pytorch.org/whl/cu117

执行这句代码又出现了新的错误，请您处理一下：

注意，需要先执行这个命令，再执行Colab中原有的代码块。

或者将这句代码插入到倒数第二行，即最后一行的!COMMANDLINE_ARGS……之上。

原理为提前手动安装正确版本的依赖。
