Gensim: TypeError: doc2bow expects an array of unicode tokens on input, not a single string

Question

I am starting with some python task, I am facing a problem while using gensim. I am trying to load files from my disk and process them (split them and lowercase() them)

Answer 1

Dictionary needs a tokenized strings for its input:

dataset = ['driving car ',
           'drive car carefully',
           'student and university']

# be sure to split sentence before feed into Dictionary
dataset = [d.split() for d in dataset]

vocab = Dictionary(dataset)
