Issue with DataFrame - TypeError: '(slice(None, None, None), 24)' is an invalid key

[shaye059]

I've tried building a tree from a pandas DataFrame using the following line:
tree = rrcf.RCTree(data_anom.sample(1000, random_state=111))

But it results in a TypeError. It works when I convert it to a NumPy array
tree = rrcf.RCTree(data_anom.sample(1000, random_state=111).to_numpy())
so is this just a matter of DataFrames not being supported or is there something in my DataFrame causing the issue?

Full error output:
