I use a python recipe to do a drop_duplicates on columns and I see that the output variables are altered.
It seems to be specific to pandas which transforms the integer with NA into a float.
So it comes that the get_dataframe function would have an argument to add in the function to overcome this and lock my variable:
And in the case of a missing value it crashes because NA does not respect the format.
