flann 1.6.13

flann is the python 3.6 bindings for FLANN - Fast Library for Approximate Nearest Neighbors.

1. Introduction

pyflann is the python bindings for FLANN - Fast Library for Approximate Nearest Neighbors.

2. Install

For python2

This package uses distutils, which is the default way of installing python modules. To install in your home directory, securely run the following:

git clone https://github.com/primetang/pyflann.git
cd pyflann
[sudo] python setup.py install

Or directly through pip to install it:

[sudo] pip install pyflann

For python3

Please refer to this issuse to modify the code.

3. Usage

Use it just like the following code:

from pyflann import *
import numpy as np

dataset = np.array(
    [[1., 1, 1, 2, 3],
     [10, 10, 10, 3, 2],
     [100, 100, 2, 30, 1]
     ])
testset = np.array(
    [[1., 1, 1, 1, 1],
     [90, 90, 10, 10, 1]
     ])
flann = FLANN()
result, dists = flann.nn(
    dataset, testset, 2, algorithm="kmeans", branching=32, iterations=7, checks=16)
print result
print dists

dataset = np.random.rand(10000, 128)
testset = np.random.rand(1000, 128)
flann = FLANN()
result, dists = flann.nn(
    dataset, testset, 5, algorithm="kmeans", branching=32, iterations=7, checks=16)
print result
print dists
