Yanbo Liang commented on SPARK-20764:
-------------------------------------
[~peng.m...@intel.com] We have test code for model summary at
[tests.py|https://github.com/apache/spark/blob/branch-2.2/python/pyspark/ml/tests.py#L1043],
but we only check the return type of summary function. For this small issue,
I'll merge it to catch 2.2. Thanks.
