tests/nested_pandas/nestedframe/test_nestedframe.py::test_get_nested_columns
  /Users/hombit/projects/lincc-frameworks/nested-pandas/src/nested_pandas/nestedframe/core.py:284: SettingWithCopyWarning:
  A value is trying to be set on a copy of a slice from a DataFrame.
  Try using .loc[row_indexer,col_indexer] = value instead

  See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
    super().__setitem__(key, value)

  /Users/hombit/projects/lincc-frameworks/nested-pandas/tests/nested_pandas/series/test_ext_array.py:1126: DeprecationWarning: __array__ implementation doesn't accept a copy keyword, so passing copy=False failed. __array__ must implement 'dtype' and 'copy' keyword arguments. To learn more, see the migration guide https://numpy.org/devdocs/numpy_2_0_migration_guide.html#adapting-to-changes-in-the-copy-keyword
