为什么会出现Could not build wheels for horovod, which is required to install pyproject.toml-based projects的报错

"Could not build wheels for horovod, which is required to install pyproject.toml-based projects" 报错通常是由于缺少依赖库或编译器导致的。具体来说，Horovod 是一个用于分布式深度学习的框架，需要使用 MPI 和 NCCL 等库进行通信。如果在安装 Horovod 的过程中缺少这些依赖库，则会导致编译 Horovod 时出现错误，从而出现该报错信息。

解决该问题的方法通常是确保在安装 Horovod 之前已经安装了必要的依赖库，并且这些库的版本与 Horovod 的要求相匹配。另外，还需要确保系统上已经安装了正确的编译器，如 GCC 或 Clang 等。如果您使用的是 Python 虚拟环境，则需要在虚拟环境中安装这些依赖库和编译器。

具体的解决方法可以参考 Horovod 官方文档或者在社区中寻求帮助。
