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
cross_validation不再可用。
尝试使用model_selection代替cross_validation:
from sklearn.model_selection import train_test_split
其他回答
它必须与model_selection的cross_validation子模块的重命名和弃用有关。尝试将cross_validation替换为model_selection
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
我猜交叉选择已经不活跃了。我们应该用模型选择来代替。您可以从sklearn编写它来运行。导入train_test_split
这是它。
Train_test_split现在在model_selection中。类型:
from sklearn.model_selection import train_test_split
应该可以
像这样更改代码
# from sklearn.cross_validation import train_test_split
from sklearn.model_selection import train_test_split
