#1612 [Issue-3617] Enables FlyteFiles, FlyteDirectors, and StructuredDatasets inputs in papermill plugin Pull request opened by peridotml TL;DR This is a first draft for allowing the papermill plugin to access more complex inputs. Type ☐ Bug Fix ☑︎ Feature ☐ Plugin Are all requirements met? ☐ Code completed ☐ Smoke tested ☐ Unit tests added ☐ Code documentation added ☐ Any pending items have an associated Issue Complete description Right now the papermill plugin can't use

FlyteFile

or

StructuredDataset

because of a Papermill limitation that everything is json serializable. My strategy is mostly copying

record_outputs

. These are the steps 1. Reserializing the inputs and save to local disk 2. Add a helper function

read_input

where users must give the input type (maybe there is a smart fix) 3.

read_input

loads the protos and uses the type to convert it to the correct format Basically I am using flyte to serialize the inputs locally (see comments), then you just need to do this.

### Params
pi = (filled in by papermill)

### In a new cell
pi = read_input(pi, float)
