As mentioned in similar Questions, i tried to convert to object fist and then convert my columns into string. However even in this step i get the same Futurewarning Error. The column Data types are ‘Object’ in the first place. so changing it again to object isn’t feasible. Interestingly when i want to change the data to sting i get this warning which indicates the column type is int64, that i don’t see any int64 dtype in df.info().
