@codesue Let's chat async what to do with https://github.com/tensorflow/model-card-toolkit/blob/master/model_card_toolkit/utils/tfx_util.py and the related tests. Are there reasons for it to stay in the MCT repo?

[hanneshapke]

I think it should probably stay. It is used in core and it seems to contain the connector pieces to the TFX libraries, not the component par se.

Let's chat async what to do with https://github.com/tensorflow/model-card-toolkit/blob/master/model_card_toolkit/utils/tfx_util.py and the related tests.

This might be good to consider as part of https://github.com/tensorflow/model-card-toolkit/discussions/228. I wonder if it's feasible to move functionality specific to pipelines and mlmd to the component's new home and the mlmd client library respectively but keep functions that only used tfma, tfdv, etc. If so, we could make tfx and mlmd utils available through a [tfx] extra, for example.
