1.用make_pipeline方便地创建管道 make_pipeline的语法: from sklearn.pipeline import make_pipeline # standard syntax pipe_long = Pipeline([("scaler", MinMaxScaler()), ("svm", SVC(C=100))]) # abbreviated syntax pipe_short = make_pipeline(MinMaxScaler(), SVC(C=100)) print("Pipeline steps:...
效用函数make_pipeline是构造管道的简写; 它需要一个可变数量的估计器并返回一个管道,自动填充名称: fromsklearn.pipelineimportmake_pipelinefromsklearn.naive_bayesimportMultinomialNBfromsklearn.preprocessingimportBinarizermake_pipeline(Binarizer(),MultinomialNB())输出:Pipeline(steps=[('binarizer', Binarizer(copy...

Make a change to the code, such as changing the title of the app. Commit the change to your repository. Go to your pipeline and verify a new run is created. When the run completes, verify the new build is deployed to your web app. In the Azure portal, go to your web app. Selec...
A pipe, or pipeline, is a special stream that, instead of having one file handle as most files do, has two. One handle is read-only, and the other is write-only. The name is very descriptive—a pipe serves to pipe a byte stream from one process to another. It’s also buffered, ...
