Effective memory management involves:

  • Using appropriate data types
  • Implementing chunking for large datasets
  • Utilizing memory-mapped files
  • Regular garbage collection
# Example: Memory-efficient processing
import numpy as np

# Memory-mapped array
data = np.memmap(‘large_array.npy’,
    dtype=’float64′,
    mode=’r+’,
    shape=(1000000,))
