AxisError: axis -1 is out of bounds for array of dimension 0

[Oliveche]

When I run preprocess.py,there is the following problem. How should I resolve it? Thanks very much!

runfile('D:/Python project/3Olive-lda2vec-master/examples/twenty_newsgroups/data/preprocess.py', wdir='D:/Python project/3Olive-lda2vec-master/examples/twenty_newsgroups/data') Traceback (most recent call last):

AxisError: axis -1 is out of bounds for array of dimension 0

In this step,i change the python interpreter to 2.7,passed the error!

The error is because of the type of self.specials.values() we have to convert it to Numpy array before sorting. In the function _loose_keys_ordered change the following line specials = np.sort(self.specials.values()) to -----> specials = np.sort(np.array([value for value in self.specials.values()]))

when i change the following line , i'm getting this error : C:\Users\fathi\anaconda3\envs\lda2vec\lib\site-packages\lda2vec-0.1-py3.6.egg\lda2vec\corpus.py:422: FutureWarning: Support for multi-dimensional indexing (e.g. obj[:, None]) is deprecated and will be removed in a future version. Convert to a numpy array before indexing instead. how to fix this ??
