@ryanthompson591 is there still work to be done on this one? If so, which test suite is it occurring in?

[ryanthompson591]

I haven't investigated this deeply.

The disabled tests are in this file
https://github.com/apache/beam/blob/master/sdks/python/apache_beam/ml/inference/sklearn_inference_test.py

For example

beam/sdks/python/apache_beam/ml/inference/sklearn_inference_test.py
