Problem and Solution

#	Problem	Solution
1	"Seed everything" requires 5+ lines of boilerplate — random.seed() + np.random.seed() + torch.manual_seed() + torch.cuda.manual_seed_all() + tf.random.set_seed() + os.environ[PYTHONHASHSEED]	RandomStateManager(seed=42) — one call seeds every framework detected in the env; .reset() rewinds mid-experiment
2	Experiment run directories collide — two parallel runs overwrite each other	gen_ID() + hash_array() — unique directory names like 20260423_2155_abc12345; deterministic array fingerprints for integrity checks

Installation

pip install scitex-repro

Python API

from scitex_repro import RandomStateManager, gen_ID, hash_array

# Cross-framework RNG seeding
rng = RandomStateManager(seed=42)
data = rng("data").random(100)
rng.verify(data, "my_data")
rng.reset()

# Deterministic IDs and array fingerprints
exp_id = gen_ID()                         # "20260423_2155_abc12345"
fingerprint = hash_array(data)

rng = RandomStateManager(seed=42)
data = rng("data").random(100)
print(gen_ID(), hash_array(data))
