reductionista opened a new pull request #481: Fix fit_multiple() warm start URL: https://github.com/apache/madlib/pull/481 The `get_initial_weights()` function in `madlib_keras.py_in` is shared by both `madlib_keras_fit()` and `madlib_keras_fit_multiple()`. But until now the code was not updated to support fit_multiple(). When called with warm-start=TRUE, this was causing improper initialization of weights for small datasets, and out-of-memory errors for larger datasets. This adds a parameter to this internal helper function, that is used to select the appropriate `mst_key` while querying the previous model output table for the weights belonging to that model.
