Pandas dataframe inside a state

[hepbc]

Hi friends,

Is there a method to add a dataframe inside a state? Saw this discussion #935 from Jul 24 where @hwchase17 mentioned that the team is working on something. Any updates to do this cleanly?

I have a graph where tools (thanks for the recent update which lets tools update states @vbarda although still to try it out) populate or edit a dataframe which is used in subsequent steps. Am trying to pass the dataframe as an artifact but the approach is very buggy and I keep getting:

ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

Request some help with this! Thanks
