pip3 install -U scikit-learn 3. 检查安装是否成功 安装完成后,你可以通过Python的交互式解释器来检查sklearn是否成功安装。运行Python解释器,然后输入以下命令: import sklearn print(sklearn.__version__) 如果没有出现错误,并且打印出了sklearn的版本号,那么说明安装成功了。 4. 使用sklearn 现在你可以开始使用...
使用pip安装sklearn库。由于sklearn库的实际名称是scikit-learn,你需要使用以下命令: bash pip install -U scikit-learn 或者如果你使用的是Python 3,并且系统同时安装了Python 2和Python 3,你可能需要使用pip3: bash pip3 install -U scikit-learn 这里的-U选项表示如果库已经安装,则更新到最新版本。 等待安...

其实是sklearn版本升级导致的,因为当版本升级后,函数的用法或者属性有所改变。一般新安装的时候会出现这个问题。可以查看一下版本:pip show scikit-learn 解决方法:fromsklearn.cross_validationimporttrain_test_split 改为:fromsklearn.model_selectionimporttrain_test_split ...
