[jira] [Updated] (SPARK-12780) Inconsistency returning value of ML
python models' properties
[ https://issues.apache.org/jira/browse/SPARK-12780?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xusen Yin updated SPARK-12780:
------------------------------
Description:
In spark/python/pyspark/ml/feature.py, StringIndexerModel has a property method named labels, which is different with other properties in other models.
In StringIndexerModel:
{code}
@property
@since("1.5.0")
def labels(self):
"""
Ordered list of labels, corresponding to indices to be assigned.
"""
return self._java_obj.labels
{code}
In CounterVectorizerModel (as an example):
{code}
@property
@since("1.6.0")
def vocabulary(self):
"""
An array of terms in the vocabulary.
"""
return self._call_java("vocabulary")
{code}
In StringIndexerModel, the returned value of labels is not an array of labels as expected. Otherwise it is a JavaMember of py4j.
