Just released v1.5.1, which should fix the underlying problems. Sorry again! The pos.teach and pos.batch-train recipes should now also be able to tell whether you want to use fine-grained or coarse-grained labels (by comparing the labels, so you don’t have to tell it explicitly). For more specific use cases, you can now even pass in a JSON tag map that maps coarse-grained to fine-grained tags.
