module 'torch' has no attribute 'concat'

根据引用\[1\]中的信息，你遇到的错误可能是因为pytorch版本改动导致的。在新版本中，torch.concat被改为了torch.cat。你可以尝试将代码中的torch.concat替换为torch.cat来解决这个问题。

另外，根据引用\[2\]中的信息，如果你在导入torchvision时遇到了"module 'torch' has no attribute '_utils_internal'"的错误，你可以尝试安装低版本的torchvision，使用命令"pip install -i https://pypi.tuna.tsinghua.edu.cn/simple torchvision==0.4.1"来安装。

希望这些信息对你有帮助！
