Я пытаюсь использовать следующий код:Ошибка при импорте scikit учиться
from matplotlib import pyplot as plt
from sklearn.datasets import load_iris
import numpy as np
Я получаю эту ошибку:
ImportError: No module named sklearn.datasets
Затем я пытаюсь установить scikit-learn, но получить эти ошибки:
pip install -U scikit-learn
File "<ipython-input-9-6d283b29f0f9>", line 1
pip install -U scikit-learn
^
SyntaxError: invalid syntax
easy_install -U scikit-learn
File "<ipython-input-10-59440c1e5ef6>", line 1
easy_install -U scikit-learn
^
SyntaxError: invalid syntax
Я использую Enthought Canopy Expresss, которые, как я думал, «The Enthought Python Distribution уже бедрами последней версии ». в соответствии с http://scikit-learn.org/stable/install.html#enthought-python-distribution
Как использовать scikit-learn?
Edit:
После установки pip через easy_install pip Затем я попытался запустить pip install -U scikit-learn и я получаю эти ошибки (из моего файла журнала):
running build_clib
No module named msvccompiler in numpy.distutils; trying from distutils
customize MSVCCompiler
Missing compiler_cxx fix for MSVCCompiler
customize MSVCCompiler using build_clib
building 'libsvm-skl' library
compiling C sources
Partial import of sklearn during the build process.

Я нахожусь на Windows. Вы хотите сказать, что мне нужно открыть командную строку и запустить эти команды? Не имеет значения, какой каталог? – user1477388
Да, это то, что я имею в виду. Неважно, какой каталог. – sashkello
