ELKI找不到类gnu/trove/impl/hash/TObjectHash
提问于 2016-01-21 09:27:39
我有一个由大约10000个样本组成的数据集，其中有两个特征。我想使用ELKI来运行LSDBC算法并对我的数据集进行聚类。然而，我还没能让ELKI去工作。在运行elki-0.7.0.jar并将我想要的设置输入gui之后，无论我选择什么设置，我都会在gui底部的控制台输入中得到一长串错误消息(我还没有能够输入所有我想要的设置)。对我来说，这表明我缺少一些依赖项，错过了一些安装步骤，或者不知何故没有正确使用软件。
不幸的是，关于ELKI的文档似乎并不多，但它也是我所能找到的仅有的LSDBC实现之一。我正在寻找的是一步一步的，ELI5，在我的数据集(它在WEKA创建的arff文件中)上安装和运行此算法的说明，并将结果输出为csv文件；即指示每个样本的聚类分配的输出文件。另外，我希望能够执行网格搜索以获得最优的k和alpha值(即，对k和alpha值的几个值运行算法并保存每个结果；然后我将确定最佳值)。我使用的是Mac OS X Yosemite。
我觉得这似乎应该是一项相对简单的任务，但我一直没有取得任何进展。我已经复制了下面得到的错误流

实际上，在JavaDoc和维基中有很多文档。
您的错误是非常基本的Java用法，实际上与ELKI无关。
从没有找到的类名可以看出(或google)
gnu/trove/impl/hash/TObjectHash
java.lang.NoClassDefFoundError: gnu/trove/impl/hash/TObjectHash您缺少ELKI Trove Java库(ELKI的一个依赖项，但不是ELKI的一部分)。也许您没有下载Maven (single-jar)版本的，而只是下载了最小版本(假设您单独管理依赖项，或者已经拥有依赖项，例如使用流行的工具)。

新的ELKI 0.7.1版本
- 包含一个自述文件，告诉您使用
elki.bat或elki.sh启动。 - 将显示更易于理解的警告，告诉您类路径不完整。
然而，ELKI的受众是知道如何读取堆栈跟踪的开发人员。
