I am working on the file "NLAhw/hw2/PS2.ipynb".
The first task is:
Write class WordVectors using provided template.
Can you write Python code for it?
 ... Can you provide a the Python code you requested?

#Here is the Python code you requested.

class WordVectors:
    
    def __init__(self, vocabulary, embedding_matrix):
        self.vocab = vocabulary
        self.W = embedding_matrix
        self.inv_vocab = {v: k for k, v in self.vocab.items()}
        
    def word_vector(self, word):
        """ 
        Takes word and returns its word vector.
        """
#         Your code is here
        return word_vector
    
    def nearest_words(self, word, top_n=10):
        """ 
        Takes word from the vocabulary and returns its top_n
        nearest neighbors in terms of cosine similarity.

model = WordVectors(vocab, W)

model.nearest_words("anarchism")
