我使用的是Ubuntu 14.04中的python 2.7。我用这些命令安装了scikit-learn, numpy和matplotlib:
sudo apt-get install build-essential python-dev python-numpy \
python-numpy-dev python-scipy libatlas-dev g++ python-matplotlib \
ipython
但是当我导入这些包时:
from sklearn.cross_validation import train_test_split
它返回给我这个错误:
ImportError: No module named sklearn.cross_validation
我需要做什么?
当前回答
sklearn。Cross_validation现在改为sklearn.model_selection
只使用
from sklearn.model_selection import train_test_split
我想那会有用的。
其他回答
sklearn.cross_validation
已改为
sklearn.model_selection
在这里查看文档: https://scikit-learn.org/stable/modules/cross_validation.html
Train_test_split是sklearn模块的一部分。因此，您可能需要从Model_selection导入模块
代码:
from sklearn.model_selection import train_test_split
将数据集分为训练集和测试集
from sklearn.model_selection import train_test_split
Cross_validation在前一段时间已被弃用，请尝试使用model_selection将其替换掉
sklearn。Cross_validation现在改为sklearn.model_selection
只改变
sklearn.cross_validation
to
sklearn.model_selection
