Installation¶

ABERRANT supports Python 3.10, 3.11, and 3.12.

Basic install¶

pip install aberrant

Optional extras¶

pip install "aberrant[eval]"      # scikit-learn metrics for evaluations
pip install "aberrant[dl]"        # deep model support (torch)
pip install "aberrant[parquet]"   # legacy parquet streamer (pyarrow)
pip install "aberrant[docs]"      # mkdocs + mkdocstrings
pip install "aberrant[dev]"       # full test/lint/type-check stack (includes torch + scikit-learn)
pip install "aberrant[benchmark]" # river + pytest-benchmark
pip install "aberrant[all]"       # all extras

Local development¶

git clone https://github.com/OliverHennhoefer/aberrant.git
cd aberrant
uv sync --extra dev --extra docs

Verify install¶

import aberrant
from aberrant.model.iforest import OnlineIsolationForest

print(aberrant.__version__)
model = OnlineIsolationForest()
print(model)

Optional dependency behavior¶

tests/models/test_deep_autoencoder.py skips when torch is not installed.
Integration tests require scikit-learn (included in aberrant[dev]).
