To answer more accurately to your question, the model.fit(df) method takes in a DataFrame of Row(label=double, feature=Vectors.dense([...])) . cheers, Ardo. On Tue, Jun 21, 2016 at 6:44 PM, Ndjido Ardo BAR wrote: > Hi, > > You can use a RDD of LabelPoints to fit your model. Check the doc for m

Hi, You can use a RDD of LabelPoints to fit your model. Check the doc for more example : http://spark.apache.org/docs/latest/api/python/pyspark.ml.html?highlight=transform#pyspark.ml.classification.RandomForestClassificationModel.transform cheers, Ardo. On Tue, Jun 21, 2016 at 6:12 PM, pseudo od

If you look at the class LabeledPoint, you'll see it has a field called "label": data.label data.features(1) would access the second element of features, which is not the same thing. On Fri, Aug 1, 2014 at 3:01 AM, SK wrote: > > Hi, > > I want to extract the indiv
