@alisoncallahan let us know if you need help with this!

thanks @hakunanatasha, this is in progress. no blockers for now, except lack of time ;-) I'm working on it today and tomorrow.

@jason-fries @hakunanatasha committed what I have so far. KB schema tests are failing because there is still weirdness in reconciling offsets with source text.

hey, @alisoncallahan thanks for helping us with this dataset! I can confirm that both load_dataset and unit-test on source config are working. However, I did encounter the same failures when compiling against the tac2017_bigbio_kb config. Additionally, you could run the command below:

python -m tests.test_bigbio_by_name biodatasets/tac2017/tac2017.py tac2017_bigbio_kb

This seems to log more details than the other test command. Hope it helps. Please don't hesitate to reach out if you have further questions!
