To highlight the actual problem: word-count-beam/src/main/java/org/apache/beam/examples/multilanguage/SklearnMnistClassification.java:[24,56] package org.apache.beam.sdk.extensions.python.transforms does not exist

I'm not sure about this suite's configuration. Does org.apache.beam.sdk.extensions.python.transforms need to be in a release before we can reference it in an example?

@kennknowles do you have context here?

Will close this when the test suite is green.
