接下来,可以安装Scikit-learn了。使用以下命令来安装: pip install -U scikit-learn 这个命令将会安装或者升级Scikit-learn到最新版本。 如果使用的是Anaconda,那么安装Scikit-learn更加简单,直接使用以下命令: conda install scikit-learn 确认Scikit-learn是否已经成功安装,可以尝试在Python环境中导入它: import sklearn ...
Scikit-learn is a powerful machine learning library that’s a great place for beginners to get their feet wet. Here’s a guide to getting started with it.
自2007年发布以来,scikit-learn已经成为最给力的Python机器学习库(library)了。scikit-learn支持的机器学习算法包括分类,回归,降维和聚类。还有一些特征提取(extracting features)、数据处理(processing data)和模型评估(evaluating models)的模块。作为Scipy库的扩展,scikit-learn也是建立在Python的NumPy和matplotlib库基础之上...
