Keras:无法导入名称np_utils

Question

我正在使用Python 2.7和Jupyter笔记本来做一些基本的机器学习.我正在关注本教程:

http://machinelearningmastery.com/regression-tutorial-keras-deep-learning-library-python/

我只是想从Keras导入不同的东西,所以我可以运行教程.具体来说,我这样做:

from keras.models import Sequential
from keras.layers import Dense
from keras.wrappers.scikit_learn import KerasRegressor
from sklearn.model_selection import cross_val_score
from sklearn.model_selection import KFold
from sklearn.preprocessing import StandardScaler
from sklearn.pipeline import Pipeline

它在第一次导入时卡住了,给我一个回溯:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-28-aae66d0fdaee> in <module>()
----> 1 from keras.models import Sequential
      2 from keras.layers import Dense
      3 from keras.wrappers.scikit_learn import KerasRegressor
      4 from sklearn.model_selection import cross_val_score
      5 from sklearn.model_selection import KFold

/Users/newscred/anaconda/lib/python2.7/site-packages/keras/__init__.py in <module>()
      1 from __future__ import absolute_import
      2 
----> 3 from . import utils
      4 from . import activations
      5 from . import applications

/Users/newscred/anaconda/lib/python2.7/site-packages/keras/utils/__init__.py in <module>()
      1 from __future__ import absolute_import
----> 2 from . import np_utils
      3 from . import generic_utils
      4 from . import data_utils
      5 from . import io_utils

ImportError: cannot import name np_utils

我已经用Google搜索了但似乎无法找出为什么我遇到这个问题/如何修复.有任何想法吗？

谢谢!

从 Keras 导入任何内容之前，请在 Python 脚本中导入 numpy。我遇到了同样的问题，在导入 numpy 实用程序（ np_utils ）之前导入 numpy 解决了这个问题。
