> Python-only UDTs can't work well. One example is:
> {code}
> import pyspark.sql.group
> from pyspark.sql.tests import PythonOnlyPoint, PythonOnlyUDT
> from pyspark.sql.types import *
> schema = StructType().add("key", LongType()).add("val", PythonOnlyUDT())
> df = spark.createDataFrame([(i % 3, PythonOnlyPoint(float(i), float(i))) for i in range(10)], schema=schema)
> df.collect()  # this works
> df.show() # this doesn't work
> {code}
