. However, despite having imported the required types from the 

typing

 library in the script where the function decorated with 

PipelineDecorator.component

 is defined, later in the generated script the 

typing

 library is not imported outside the scope of the function

Actually the typing part is not passed to the "created step" , because there are no global imports, for eexample:
def step(a: pd.DataFrame): import pandas as pd passThe imports are in the function step (we cannot move them outside without a very fragile code analysis) so the created function Task will not had pands imported on the global scope and you will end up with an exception "pd not defined".
Make sense?
