----------------------------------
Summary: Fix fit_multiple when output_table or mst_table is passed
as NULL
Key: MADLIB-1464
URL: https://issues.apache.org/jira/browse/MADLIB-1464
Project: Apache MADlib
Issue Type: Bug
Components: Deep Learning
Reporter: Nikhil Kak
Fix For: v1.18.0
Currently while calling fit_multiple, if we pass NULL to either the
output_table argument or the mst_table argument, it fails with the wrong error
message.
NULL output_table
```
select madlib.madlib_keras_fit_multiple_model(
'iris_data_packed',
NULL,
'mst_table',
2, FALSE, NULL, 1);
ERROR: AttributeError: FitMultipleModel instance has no attribute
'model_info_table'
```
NULL mst_table
```
select madlib.madlib_keras_fit_multiple_model(
'iris_data_packed',
'iris_multiple_model',
NULL,
2, FALSE, NULL, 1);
ERROR: AttributeError: FitMultipleModel instance has no attribute
'model_selection_summary_table' (plpy_elog.c:121)
```
The model hopper refactor PR https://github.com/apache/madlib/pull/525 has a
fix for the NULL output_table (but the error message isn't consistent with
other modules) but the null mst_table failure still exists.
