Maybe not working in python3, intermitant "Caught exception: Unknown algorithm for choosing inital centers" error

[HenryDayHall]

So I don't really know what I'm doing with this package, apologies if this is a error on my end. The error message "Caught exception: Unknown algorithm for choosing initial centers." seems to appear intermittently when trying to chose an algorithm with a string, and no matter what I put in the result is [0, 0].

I am using python 3.6.7 with ipython 7.1.1.

Here is an example;

testset = np.random.rand(1000, 128)
    ...: flann = pyflann.FLANN()
    ...: result, dists = flann.nn(
    ...:     dataset, testset, 5, algorithm="kmeans", branching=32, iterations=7, checks=16)
Caught exception: Unknown algorithm for choosing initial centers.   
#^^ Error here!!!!!!!

In [31]: dataset = np.random.rand(10000, 128)
    ...: testset = np.random.rand(1000, 128)
    ...: flann = pyflann.FLANN()
    ...: result, dists = flann.nn(
    ...:     dataset, testset, 5, algorithm=0, branching=32, iterations=7, checks=16)

In [32]: results
Out[32]: array([0, 0], dtype=int32)

In [33]: dataset = np.random.rand(10000, 128)
    ...: testset = np.random.rand(1000, 128)
    ...: flann = pyflann.FLANN()
    ...: result, dists = flann.nn(
    ...:     dataset, testset, 5, branching=32, iterations=7, checks=16)

In [34]: results

In [35]: dataset = np.random.rand(10000, 128)

    ...: result, dists = flann.nn(
    ...:     dataset, testset, 5, algorithm=0, branching=32, iterations=7, checks=16)

In [36]: dataset = np.random.rand(10000, 128)

#^^ Same code no error!!!!!!!

In [37]: print(results)
