Use a.empty, a.bool(), a.item(), a.any() or a.all().

What is going on with this? Running it on redhat 7

Hi!

This is probably a bit late but I guess your list_id object is not a list but either a pandas.Series or a numpy.ndarray. This is why it fails like that when we are doing if not ids_origin: instead of doing something like if ids_origin is not None:.

OH that makes sense- thank you
