Fasttext: '_FastText' object has no attribute 'get_nearest_neighbors'

Here we can see that there is no attribute get_nearest_neighbors but official documentation demands get_nearest_neighbors

install fasttext via the github repo instead!

[Rajan-sust]

Thanks. It's working now.

I still have this problem even after installing the library from the github repo via
>>> git clone https://github.com/facebookresearch/fastText.git
>>> cd fastText
>>> python3 setup.py install
and I get the same output as in the original comment for dir(model)

I am trying to install fasttext from the github repo but I am on windows and make is not working out (I installed it using MinGW). I'm getting the following error:

Ok so my issue was that I am on windows and I did not have C++11 installed. I managed to install it using MinGW-w64. Now it worked out but I am getting the following error (PS: I am using fasttext for Arabic ==> cc.ar.300.bin):

ft.get_nearest_neighbors('فلسطين'):
{Attribute Error}: fasttext_pybind.fasttext object has no attribute 'getNN'

No I am also not able to save the model:

model_path = 'E:/cc.ar.300.bin/cc.ar.300.bin'
    path = 'E:/cc.ar.300.bin/'
    file = 'cc.ar.300.bin'

    t1 = time.time()
    ft = fasttext.load_model(model_path)
    t2 = time.time()
    print('fasttext dimension: {}'.format(ft.get_dimension()))

    # reduce the dimension fromm 300 to 200 and save
    fasttext.util.reduce_model(ft, 200)
    print('fasttext dimension: {}'.format(ft.get_dimension()))
    ft.save_model(os.path.join(path, 'cc.ar.200.bin'))

    fasttext.util.reduce_model(ft, 100)
    print('fasttext dimension: {}'.format(ft.get_dimension()))
    ft.save_model(os.path.join(path, 'cc.ar.100.bin'))

Gives the following errors:

Warning : `load_model` does not return WordVectorModel or SupervisedModel any more, but a `FastText` object which is very similar.
