SparseSeries deprecated: scipy-dev failing on travis #14002
Description
test_type_of_target is failing on scipy-dev because it uses pd.SparseSeries:
FutureWarning: SparseSeries is deprecated and will be removed in a future version.
Use a Series with sparse values instead.
>>> series = pd.Series(pd.SparseArray(...))
