Breaking changes: tfma.metrics.MetricComputation `preprocessor` argument changed from accepting beam DoFn to `preprocessors` accepting a list of `Preprocessor`

[EdwardCuiPeacock]

Recent release of TFMA (0.42 - 0.43 - master) changed the DoFn argument from preprocessor

model-analysis/tensorflow_model_analysis/metrics/metric_types.py

Line 396 in a5c4c70

('preprocessor', beam.DoFn),

to preprocessors

model-analysis/tensorflow_model_analysis/metrics/metric_types.py

Line 440 in e1c34a8

('preprocessors', List[Preprocessor]),

This breaking change is not reflected in the example for custom metrics here.

@EdwardCuiPeacock,

Thank you for pointing this out.

@mdreves, Can you please take a look into custom TFMA metrics example. The example is not updated as per the change in preprocessors attribute in MetricComputation. Thank you!
