決定木分析で警告エラー

Question

次のPythonプログラムを実行すると、
警告文「VisibleDeprecationWarning」が出ます。
どうしたら警告文が消えますか？
実行環境はgoogle colaboratoryです。

[警告エラー]
/usr/local/lib/python3.7/dist-packages/numpy/core/_asarray.py:83: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray
return array(a, dtype, copy=False, order=order)
