Hi! I am currently testing the new prodigy integration to visualize NER datasets and it works great, thank you! But I have some problems.  
I would like to filter `row["spans"]["label"] ` by the special entities and I have problems here. My use case:

- Which texts contain only people (PERSON)? Which organisations (ORG) or locations (LOCATION)? How many people do I find in total?
- I would like to create new rows/columns to visualize the results.

My problem: I can’t manage to filter according to the entities. What am I doing wrong?  
Your example here is also ok for the test:

Thank you

Glad you’re enjoying the prodigy integration!

I’ll try get an answer for this for you ASAP.

I don’t know what I did wrong last time, but it works perfectly. Thanks!
