我正在尝试聚集一个csv文件格式的样本数据集。但是当我给出下面的命令时，
user@ubuntu:/usr/local/mahout/trunk$ bin/mahout kmeans -i /root/Mahout/temp/parsedtext-seqdir-sparse-kmeans/tfidf-vectors/ -c /root/Mahout/temp/parsedtext-kmeans-clusters -o /root/Mahout/reuters21578/root/Mahout/temp/parsedtext-kmeans -dm org.apache.mahout.common.distance.CosineDistanceMeasure -x 2 -k 1 -ow --clustering -cl
我收到以下错误，说没有可用的输入群集并检查-c群集参数。请有人帮助我吗>
以下是我对上述命令的错误：
16/05/11 16:09:15 INFO compress.CodecPool: Got brand-new decompressor [.deflate]
Exception in thread "main" java.lang.IllegalStateException: No input clusters found in /root/Mahout/temp/parsedtext-kmeans-clusters/part-randomSeed. Check your -c argument.

答案 0 :(得分：2)
让我为您复制错误消息：
在/ root / Mahout / temp / parsedtext-kmeans-clusters / part-randomSeed中找不到输入集群。检查你的-c参数。
您是否考虑过检查或删除-c参数？
但是Mahout k-means实际上是低质量的。使用别的东西。 apt-get install elki并尝试相反，它会更快。
