COVER // HOW WOULD YOU APPROACH OPTIMIZING NUMPY ARRAY OPERATIONS FOR A LARGE-SCALE DATA PROCESSING APPLICATION, PARTICULARLY WHEN DEALING WITH MEMORY CONSTRAINTS?

To optimize NumPy array operations under memory constraints, I would utilize memory-mapped files with NumPy’s memmap functionality, which allows large arrays to be stored on disk but accessed as if they are in memory. Additionally, I would focus on leveraging in-place operations and avoiding unnecessary copies of data to minimize memory usage.
