Installation

pip install qis

qis requires Python 3.10 or later. The core install pulls only the scientific stack: numpy, pandas, scipy, statsmodels, numba, matplotlib, seaborn, openpyxl and PyYAML. No data-vendor client is installed by default.

Optional extras

extra	adds	for
data	yfinance, pandas-datareader	downloading prices in examples
io	pyarrow, fsspec	parquet and feather
reports	pybloqs, jinja2	HTML and PDF factsheet rendering
visualization	plotly	interactive figures
database	psycopg2, SQLAlchemy	database-backed storage
jupyter	jupyter, notebook, jupyterlab	notebook use
all	every extra above

pip install "qis[data,io]"

The analytics core never imports an optional dependency at module level. Where one is needed, the import is function-local and raises an ImportError naming the extra.

From source

git clone https://github.com/ArturSepp/QuantInvestStrats.git
cd QuantInvestStrats
pip install -e ".[data,io]"
pytest

The test suite passes on a core install; tests needing an extra are skipped, not failed.
