我正在尝试在 Windows 10 x86_64 系统中从ultralytics安装 PyTorch YOLOv5。说明看起来很简单，在为 GPU 安装 PyTorch 后，我尝试使用以下命令安装所需的要求：pip install -qr https://raw.githubusercontent.com/ultralytics/yolov5/master/requirements.txt
我得到以下错误日志：

我已安装 Microsoft C++ Build Tools 并在 CMD 中获得以下输出：
** Visual Studio 2019 开发人员命令提示符 v16.9.6 ** 版权所有 (c) 2021 Microsoft Corporation
我正在尝试重新安装 requirements.txt，但 Microsoft C++ Build Tools 的错误仍然存在。
我应该怎么办？
