Learn how to grab data from a CSV (comma-separated values) file and save the data to Azure Blob Storage. Transform the data and save it to a staging area. Then train a machine learning model by using the transformed data. WebThe pipeline has all the methods that the last estimator in the pipeline has, i.e. if the last estimator is a classifier, the Pipeline can be used as a classifier. If the last estimator is a transformer, again, so is the pipeline. 6.1.1.3. Caching transformers: avoid repeated computation¶ Fitting transformers may be computationally expensive.
