{A_DIRECTORY}\.tox\py37\lib\site-packages\openpyxl\compat\numbers.py:41: DeprecationWarning: `np.float` is a deprecated alias for the builtin `float`. Use `float` by itself, which is identical in behavior, to silence this warning. If you specifically wanted the numpy scalar type, use `np.float_` here.
