What does it do?

Generate the 11 statistical features from a 2d numpy array which has metrics as columns and timeseries as rows. Approximately 50 times faster than python.

Usage

from fast_features import generate_features
# df is the standard timeseries dataframe
features = generate_features(df.values)

Installation

Two binary packages are provided with this repository, and can be installed in the following way:

Make sure that you upgrade pip before installing the wheel.

For python 3.6.x: ${PIP} install ./dist/fast_features-0.1.0-cp36-cp36m-linux_x86_64.whl

For python 3.7.x: ${PIP} install ./dist/fast_features-0.1.0-cp37-cp37m-linux_x86_64.whl

If there are any incompatibilities with libc version, then the package needs to be compiled from source:

Compilation

Compiling this python package requires Rust, which requires a working C compiler.

First insall Rust nightly (necessary because of PyO3)

1. curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
2. rustup toolchain install nightly
3. rustup override set nightly Then install necessary python packages and compile using setup.py
4. pip3 install --user -r requirements.txt
5. python3 setup.py sdist bdist_wheel After this, install the fast_features package using the above pip install command.
