在QuantConnect的本地平台中，Docker的安装路径是指向您想要使用的Docker安装的路径。这个路径应该是Docker可执行文件的路径。在Ubuntu系统中，这个路径通常是
/usr/bin/docker。如果您已经安装了Docker，但是本地平台无法检测到它，您需要更新您的"Executable Path: Docker"设置，使其成为您的Docker可执行文件的路径。
以下是如何查看和更改本地平台扩展设置的步骤：
在这里，您可以找到并更改"Executable Path: Docker"的设置。

我是否可以通过windows上的本地平台通过samba协议调用局域网内Ubuntu系统上的docker和lean进行回测？如果能我需要怎么做？
Mia Alissi
对不起，根据我所拥有的信息，我无法确定QuantConnect的本地平台是否支持通过Samba协议在Windows上调用局域网内Ubuntu系统上的Docker和LEAN进行回测。我建议您查阅QuantConnect的官方文档或者在QuantConnect的论坛上寻求更多的帮助。

如何创建虚拟节点
Mia Alissi
在QuantConnect的本地平台中，当您运行多个回测或研究笔记本时，会自动创建"虚拟节点"。每个回测或笔记本都在同一主机机器上的单独容器中运行，这就是所谓的"虚拟节点"。您可以运行尽可能多的并行回测或笔记本，只要您的CPU和RAM能够处理。
要查看所有的虚拟节点，您可以查看资源面板。
请注意，您无需手动创建虚拟节点，它们是在运行多个回测或笔记本时自动创建的。
