Python ValueError

Question

Hello, I am getting the error "ValueError: could not broadcast input array from shape (0,) into shape (100,)"

while trying to execute the below code. How can I resolve this?

embeddings_index = {}

embedding_dim = 100

f = 'glove.twitter.27B.100d.txt'

for line in f:

    values = line.split()

    word = values[0]

    coefs = np.asarray(values[1:], dtype='float32')

    embeddings_index[word] = coefs


print('Found %s word vectors.' % len(embeddings_index))

embedding_matrix = np.zeros((len(word_index) + 1, embedding_dim))

c = 0

for word, i in word_index.items():

    embedding_vector = embeddings_index.get(word)

    if embedding_vector is not None:

        c+=1

        embedding_matrix[i] = embedding_vector

print(c)
