Hi @aliao, thanks for the suggestion but the TFX Evaluator is being run with Beam (as I initiated this job on Vertex) so I can’t check the logs as you’ve indicated. There doesn’t appear to be any mention of tensorflow_decision_forests in the logs that I can see (can be viewed in this gist: Evaluator logs · GitHub 1).
I can see in the JSON file generated by the tfx.dsl.Pipeline API call that it’s specifying the TFX version as 1.5.0 and the image to use for the Evaluator as gcr.io/tfx-oss-public/tfx:1.5.0. I included this file in the above Gist.
