Install

pip install aether-quant is the research install: the library and the aq command on numpy and pandas only. It does not pull torch, Lean, Docker, Redis or Postgres. Add an extra for each thing you need.

Command	Adds	For
pip install aether-quant	numpy, pandas	the library, aq hello, every facade (about 145 MB in a fresh venv)
pip install "aether-quant[research]"	scipy, scikit-learn, statsmodels, pyarrow, httpx	HRP, the gradient-boosted probes, parquet research files, FRED
pip install "aether-quant[notebooks]"	research + matplotlib, ipykernel, nbclient	the tutorials
pip install "aether-quant[dashboard]"	fastapi, uvicorn	serving the dashboard API
pip install "aether-quant[live]"	redis, psycopg, keyring, ibapi, the Lean CLI	paper and live deployments
pip install "aether-quant[train]"	torch, scikit-learn, pyarrow	retraining the models
pip install "aether-quant[docs]"	mkdocs-material, mkdocstrings, mkdocs-jupyter	building this site
pip install "aether-quant[full]"	everything above	the whole system

The Lean engine image (about 40 GB) is only for real Lean backtests and deployments of the trading system. No research path needs it.

From a clone

git clone https://github.com/leon1706-lol/Aether-quant
cd Aether-quant
pip install -e ".[research]"
aq hello --offline

What a light install can do

Every facade imports with only numpy and pandas present (tests/test_lite_install.py blocks every optional package and checks). A function that needs an extra imports it when called. For example, compute_hrp_weights needs scipy, so it raises ModuleNotFoundError on a light install and works after pip install "aether-quant[research]".
