Memory usage tests were run in T339890#9155985, T339890#9156601, T339890#9159257, and T339890#9162780. The 4th test where float was downcasted to np.float32 and numpy arrays preprocessed, resulted in a 5x drop in memory usage. This was the best result of the 4 tests performed.
In this task we will work on adapting the recommendation-api to fetch and use the float32 preprocessed numpy arrays from swift.
