What might be the cause of 'invalid value encountered in less_equal' in numpy

I experienced a RuntimeWarning

 RuntimeWarning: invalid value encountered in less_equal

Generated by this line of code of mine:

Answer 1

This happens due to Nan values in dataframe, which is completely fine with DF.

In Pycharm, This worked like a charm for me:

import warnings

warnings.simplefilter(action = "ignore", category = RuntimeWarning)
