Hi, I’ve made successful pos.teach, pos.make-gold, pos.gold-to-spacy results into dataset.

But suddenly when I tried to train a model using pos.batch-train, or pos.train-curve, it wasn’t working at all with the same error of below link

[[Errors with pos.teach and pos.batch-train.](https://support.prodi.gy/t/errors-with-pos-teach-and-pos-batch-train/599)]

so as they said, I just remove the code from the pos.py very simply, and it was looked working seamlessly on first, but I have still annoyed by below error message, I couldn’t find where that problem is coming from

can someone help me out?

Just to confirm: Are you using the latest version of Prodigy, `v1.5.1`? The recent version introduced a few changes to the POS recipes, so if you’re still on the previous version, it might be related to that. You could also try adding a print statement to see which examples it fails on, and double-check that all examples in your set are POS annotations in the expected format.
