Oh, sorry, I actually can reproduce it locally.

Turns out arrays in numpy 1.15 don't have __array_function__. So this:

python if deep: if hasattr(data, "__array_function__") or isinstance( data, dask_array_type ): data = copy.deepcopy(data) elif not isinstance(data, PandasIndexAdapter): # pandas.Index is immutable data = np.array(data)

could just be

python if deep and not isinstance(data, PandasIndexAdapter): data = copy.deepcopy(data)

But I'm not familiar with __array_function__ or why it's being used here, any thoughts?
