"Read Sparse operator has problem with Weka-based operators"

Hi forum,

I have just designed a simple process which a "Read Sparse" operator delivers the data to a weka hierarchical clustering operator (W-HierarchicalCluster). In runtime, I see an error which says that, the array bound is out of the expected range. My dataset has 2000 columns but RM wants to access columns 2001 !!!.
I am really familiar with read "sparse operator" and I have used it always with RM original operators without any problem. but Now I just need to use it with WEKA HierarchicalClustering operator. The strange thing is that I have no problem with using the same Read Sparse operator with an original RM clusterer like KMEans(Fast).

Any help on this issue will be greately appreciated.

    Does a message box popup with the option to submit a bug? If so, please submit a bug to our bugtracker. RapidMiner will then automatically attach valuable information to hunt down the bug.

    Does the error only occur with the Read Sparse operator, or also with the normal read operators?

    Best, Marius

    Hi Marius,


    No, I have not any problem with other read operators.

    What about the bug report dialog, does it appear? It contains something called a "stacktrace", which tells us developers exactly which error occured and where.

    Best, Marius
