Java.lang.reflect.InvocationTargetException

Error, the Weka run package did not give detailed error information and could not be found.

Direct debugging Weka Source code, found m_maxc=infinity, it seems that the data has illegal characters.

It seems to encounter such errors, or first look at their own data there is no error, weka after all is open source free, the error is not so detailed.

There are illegal values in the KPI:
