Custom transformers sklearn

WebYour task in this assignment is to create a custom transformation pipeline that takes in raw data and returns fully prepared, clean data that is ready for model training. However, we will not actually train any models in this assignment. This pipeline will employ an imputer class, a user-defined transformer class, and a data-normalization class. WebThen lets write the saving code to pickle just inside the same file . ( Don't create an external .py file src.feature_extraction.transformers to define your customtransformers ). Then fit and dumb your pipeline by running that file. Create a customthings.py file with all the functions and transformers defined inside.
