Use the package manager to install:
pkg> add FLANN
Usage Example
using Distances
using FLANN
X = readdlm(Pkg.dir("FLANN", "test", "iris.csv"), ',')
v = X[:, 84]
k = 3
r = 10.0
idxs, dsts = knn(X, v, k, FLANNParameters())
# or
t = flann(X, FLANNParameters(), Minkowski(3))
inds, dists = knn(t, v, k)
# or
idxs, dsts = inrange(t, v, r)
# Do not forget to close index!
close(t)TODO
