我得到了同样的错误(“Das系统kann die angegebene Datei nicht finden”,仅用英语)。您可以尝试在site packages/torch/utils/cpp_extension.py中找到打印此文件的行(我的是第184行),然后在warnings.warn语句之前插入这些行,这样您就可以看到torch试图查找编译器的确切位置,然后您可以绕过编译器路径使其适合您,但这当然只是一种黑客行为,并不是最好的解决方案:打印(编译器);导入回溯;traceback.print_exc()我得到了同样的错误(“Das System kann die angegebene Datei nicht finden”,仅用英语)。您可以尝试在site packages/torch/utils/cpp_extension.py中找到打印此文件的行(我的是第184行),然后在warnings.warn语句之前插入这些行,这样您就可以看到torch试图查找编译器的确切位置,然后您可以绕过编译器路径使其适合您,但这当然只是一种黑客行为,并不是最好的解决方案:打印(编译器);导入回溯;traceback.print_exc()
