    Default Connect weka to python

    I tried to send a numpy object to Weka package using java bridge
    but i got the below error.

    'numpy.ndarray' object has no attribute 'jobject'
    what the best way to convert numpy.ndarray to jobject?

    Are you using the wekaPython package? If so, then only pandas data frames and images are transferable back into Weka (the former are converted to ARFF via CSV; and the later are transferred as base 64 encoded png data). All other variables are returned to Weka in string form. I have never seen the error you report.
