Ao executar o código para match, encontro esse erro

Traceback (most recent call last):
  File "classificacao.py", line 13, in <module>
    from sklearn.naive_bayes import MultinomialNB
  File "C:\Python35\lib\site-packages\sklearn\__init__.py", line 57, in <module>
    from .base import clone
  File "C:\Python35\lib\site-packages\sklearn\base.py", line 10, in <module>
    from scipy import sparse
ImportError: No module named 'scipy'

instalei corretamente o scikit-learn, não sei o qque deve ter ocorrido, esse é o meu código:

# eh gordinho? tem perninha curta? se faz au au?
porco1 = [1, 1, 0]
porco2 = [1, 1, 0]
porco3 = [1, 1, 0]
cachorro1 = [1, 1, 1]
cachorro2 = [0, 1, 1]
cachorro3 = [0, 1, 1]

dados = [porco1, porco2, porco3, cachorro1, cachorro2, cachorro3]

marcacoes = [1, 1, 1, -1, -1, -1]

from sklearn.naive_bayes import MultinomialNB

modelo = MultinomialNB()
modelo.fit(dados, marcacoes)

misterioso1 = [1, 1, 1]
misterioso2 = [1, 0, 0]
misterioso3 = [0, 1, 1]
teste = [misterioso1, misterioso2, misterioso3]
print(modleo.predict(teste))

  `setup.py clean` is not supported, use one of the following instead:

    - `git clean -xdf` (cleans all files)
    - `git clean -Xdf` (cleans all versioned files, doesn't touch
                        files that aren't checked into the git repo)

  Add `--force` to your command to use it anyway if you must (unsupported).
