I was using 3 functions form scipy: TFIDF vectorizer, Multioutput classifier and Linear SVC.

The code goes like this.

pipe_lr1 = Pipeline(steps=[('cv',TfidfVectorizer()), ('lr_multi',MultiOutputClassifier(LinearSVC()))])

How can I print the values at each step of the function in order to see

  • What was the ouptput of TFIDF vectorizer?
  • What was the output of Linear SVC?
  • What data was coming out of MultioutputClassifier(X)?

You can access them using the below code. Do what you normally do without using a pipeline.

  • $\begingroup$ This is not print anything; it gives you access to TfidfVectorizer and MultiOutputClassifier. Then use their functions. For example pipe_lr1.named_steps["cv"].get_feature_names_out() $\endgroup$
