Question

使用斯坦福主题建模工具包tmt执行PLDA的代码示例会导致"scala.tools.nsc.MissingRequirementError: object scala not found"错误。

按照斯坦福大学TMT webpage的指示，我下载并运行tmt script。这会启动应用程序。然后，我下载了必需的data，将其用作PLDA脚本的输入。但是，在执行PLDA的脚本时，会引发以下错误。

由于我不知道scala是如何工作的，因此我不确定这里缺少什么以及如何成功对PubMed数据执行PLDA脚本。

任何提示或指示都值得赞赏。

是什么导致Stanford Topic Modeling工具箱中的MissingRequirementError：object scala not found错误？
