Ray群集配置文件\u mounts部分不允许启动工作节点

Question

我正在使用配置中的file\ mounts块，尝试将少量文件分发到awsec2上的Ray集群中的每个节点文件：-你知道吗

文件\u装载：{ “/”：“/运行\u文件” }你知道吗

集群启动时只有一个主节点，run\u files目录的内容已正确复制到该节点上。但是，请求的两个工作节点不会启动。如果我省略file\u mounts部分，workers将启动。光线监视器指示查找文件时出现问题libtcl.so文件在Anaconda3安装的matplotlib子目录中。此文件位于主节点上的正确路径上，因此工作节点上的设置似乎不起作用适当地：-你知道吗

（请注意，这个问题是继“Workers not being launched on EC2 by ray”问题之后出现的，我在一个新问题中继续讨论，因为现在更明确地确定了错误的来源。）

Answer 1

我认为libtcl.so文件错误消息非常容易误导。问题是文件\u mounts remote path不能是worker上的主目录（也不能是./nor~/works）；它必须是子目录。所以下面是s成功：你知道吗

file_mounts: {"~/run_files": "./run_files"}
