Sequences (1.24+) are breaking how panthera works, basically this works:

(pt/data-frame (vec (flatten (repeat 5 [{:a 1 :b 2} {:a 2 :b 3}]))))
But this doesn't:

(pt/data-frame (flatten (repeat 5 [{:a 1 :b 2} {:a 2 :b 3}])))

flatten is a LazySeq.

The reason this is breaking since 1.24+ is that in 1.24+, @cnuernber changed it so that lazy seqs do not fully realize before they're passed in to Python.

This is to allow infinite sequences from Clojure to be passed in to Python. Technically, the behavior from before 1.24 was a bug -- lazy seqs should not be fully realized in Python.

Ah sorry to hear that. I was hoping this would fix but looks like it might be more complex than we thought.
