我正在尝试使用weka Package 器对python中的Dataframe进行功能选择：

def featureSelection(self):
    search = ASSearch(classname="weka.attributeSelection.BestFirst", options=["-D", "1", "-N", "5"])
    evaluator = ASEvaluation(classname="weka.attributeSelection.CfsSubsetEval", options=["-P", "1", "-E", "1"])
    attsel = AttributeSelection()
    attsel.search(search)
    attsel.evaluator(evaluator)
    attsel.select_attributes(self.dataset) # This is where the error happens
    print("# attributes: " + str(attsel.number_attributes_selected))
    print("attributes: " + str(attsel.selected_attributes))
    print("result string:\n" + attsel.results_string)

我得到这个错误：
attributeerror:“dataframe”对象没有属性“jobject”
我只得到 object , int64 ，和 float64 当我检查Dataframe时。
我该怎么办？提前谢谢！
