pymilvus_orm安装失败

在学习使用milvus2.0版本时，win10操作系统，py3本地连接milvus时，需要安装官方工具包pymilvus_orm，这个时候会自动安装一些其他的依赖包，但是安装mmh3=2.3.1时失败了，本地能够安装mmh3==3.0.0版本的。报错如下：

解决办法

正如上面的说明，是因为编译安装的时候mmh3==2.3.1版本的int32_t、uint32_t与c++环境的stdint.h的定义不同。导致无法覆盖安装失败。经过查看如下图：
stdint.h文件：

mmh3module.cpp文件

只需要修改stdint.h文件的两个int为long型，保存，再次安装就可成功。
