khannaekta opened a new pull request #454: DL: Fix miscellaneous bugs
URL: https://github.com/apache/madlib/pull/454
 
 
   This PR fixes the following issues:
   1. Fix crash in `madlib_keras_fit_multiple_model()` for user inputed one-hot encoded data(y)
   2. Avoid GPU memory issues caused due to long lasting processes left from queries creating TEMP tables.
   3. Avoid creating unnecessary multiple slices (which might lead to GPU memory issues) using distribution_key instead of gp_segment_id
   4. Fix `madlib_keras_predict()` not to display the following warning: 
        ```
       WARNING:  column "attributes_shape" does not exist
      CONTEXT:  PL/Python function "madlib_keras_predict"
      madlib_keras_predict
      ----------------------
        ```
   5. Add E2E test for `madlib_keras_fit()` and `madlib_keras_fit_multiple_model()`.
   
   Note: Some tests in `madlib_keras_model_selection_e2e.sql_in` can be uncommented once PR #451 is merged
   
   - [x] Add the module name, JIRA# to PR/commit and description.
   - [x] Add tests for the change.
