我正在尝试通过gremlin控制台连接到gephi（0.9.1）。我的泰坦数据库中有一个图表。我也在我的gephi中启用了流媒体服务器。通过gremlin我执行了以下命令：
所有这些都运行良好。但是当我运行最后一个命令时：
var query = context.Rule.Where(r => r.IsActive && !context.Exclusion.Any(e => e.ApplicationId == applicationId && e.SiteId==siteId && r.Id==e.RuleId))
我收到以下错误：
:> g
而且我经常得到：

我已检查打开的端口，我还发现8080端口已打开。

请注意，Gephi Plugin最近才与TinkerPop 3.2.1-SNAPSHOT a few days ago的Gephi 0.9.x兼容。当你使用Titan 1.0时，我猜你有一个旧版本。如果你希望一切都能无缝地工作，我建议你回到Gephi 0.8.x beta。
所有这一切，你可能还能够让它发挥作用。 Gephi提供的默认工作区不再是“workspace0” - 它现在从“1”开始索引。您可以通过执行以下操作来更改Gremlin远程使用的工作区：
:remote config workspace workspace1
这应该允许将数据发送到Gephi，它应该显示在“实验室”窗格中。您可能还有可视化问题。我发现在解决这个问题时，不能将“大小”，“x”和“y”属性自动设置为“合理”的东西似乎阻止了可视化窗格显示顶点和边缘。我认为你需要将这些属性添加到你想要推送到Gephi的任何图形中。我做的补丁将大小设置为“10”，x / y设置为随机浮动 - 将它们全部设置为零/零（即相同的位置）不起作用。
以上所有解决方法说明主要用于提供信息。下载Gephi 0.8.x时，您可能需要做很多额外的工作，这是一个非常简单的操作过程。
