“TypeError: Already tz-aware, use tz_convert to convert.” when I update pandas

问题

I have update pandas from 0.20 to 0.21.1 (anaconda distribution) and I have an message error: "TypeError: Already tz-aware, use tz_convert to convert." when I executed this code with python 0.20 it worked perfectly !!

 PvBrut['Date'] = PvBrut.Date.dt.tz_localize('UTC').dt.tz_convert('Europe/Paris')+timedelta(minutes=5)
