How can I optimize memory usage in NumPy?
You can optimize memory usage in NumPy by using smaller data types, avoiding copies, and using views instead of copies.
What are some smaller data types I can use?
You can use float32
instead of float64
, or int8
instead of int64
to save memory.
How do I avoid making copies of arrays?
