joblib
A Python serialization library optimized for NumPy arrays and machine learning models. It supports memory mapping and compression options, offering superior performance compared to the standard pickle module when handling large numerical datasets.
Timeline (last 90 days)
joblib is optimized for numpy arrays and large models, offering faster read/write for large arrays and supporting compression, but it is an external dependency.
joblib.dump() accepts a compress parameter (values 1–9) to trade off between file size and read/write speed.
If a model internally contains large numpy arrays (as is common with scikit-learn models), joblib has advantages over pickle in both speed and reliability.
The sklearn.externals.joblib used in early code is deprecated, and the standalone joblib package should be used directly.
