VW is missing

运行结果如上

尝试重新安装VW34库，不确定是否由这个库引起还是缺依赖项

成功安装scenelib

Answer 1

"VW location is missing" 是在安装 scenelib 时出现的一种错误。这通常是因为 scenelib 依赖 Vowpal Wabbit (VW) 来进行训练，而 VW 尚未安装或者路径未被正确配置。

解决这个问题的方法有以下几种：

安装 Vowpal Wabbit (VW)。这可以通过下载源代码并编译安装来完成。

检查 Vowpal Wabbit (VW) 的安装路径是否正确。您可以在运行 configure 文件之前，手动设置 VW 路径。例如：./configure --with-vw=/usr/local/vw。

如果你还是不能解决问题,建议查看scenelib的安装文档或者在scenelib 的开发者社区中寻找解决方案。

总之,在安装 scenelib时，需要确保 Vowpal Wabbit (VW) 已经安装并且路径已经正确配置。如果您在执行 ./configure 时出现 "VW location is missing" 错误，请检查 VW 是否已经安装并且路径是否正确，或者手动设置 VW 路径。如果问题仍然存在，建议查看 scenelib 的安装文档或在 scenelib 的开发者社区中寻找解决方案。
