This would > allow using Table objects in plasma and DataFrames can be converted to a > Table object as intermediary for serialization. Currently I see the following > when trying this operation: > {code:java} > In [36]: pa.serialize(t) > --------------------------------------------------------------------------- > SerializationCallbackError Traceback (most recent call last) > <ipython-input-36-48cee5dfe30a> in <module>() > ----> 1 pa.serialize(t) > ~/dev/arrow/python/pyarrow/serialization.pxi in pyarrow.lib.serialize() > 336 > 337 with nogil: > --> 338 check_status(SerializeObject(context, wrapped_value, > &serialized.data)) > 339 return serialized > 340 > ~/dev/arrow/python/pyarrow/serialization.pxi in > pyarrow.lib.SerializationContext._serialize_callback() > 134 > 135 if not found: > --> 136 raise SerializationCallbackError( > 137 "pyarrow does not know how to " > 138 "serialize objects of type {}.".format(type(obj)), obj > SerializationCallbackError: pyarrow does not know how to serialize objects of > type <class 'pyarrow.lib.Table'>. > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
