Changelog¶

1.1.0 (2021-05-07)¶

MemoizedGroup is now picklable. This makes it usable by multiprocessing-based parallelism.
Memoized and MemoizedGroup are now thread-safe.
Improved log messages.
determ_hash(obj) uses a hash of the pickle.dumps. This makes it accept more datatypes such as numpy.int64, which could not be hashed by the old determ_hash. determ_hash still falls back to hashing-by-attributes for non-picklable objects.
The time_cost used to over-estimate (include the time which would have been spent in the non-memoized case as well (recomputing f(x))).
Tweaked documentation.
with_attr(..., "key", lambda: key) replaces KeyVer(key, ver).
