看看这个SO问题，你似乎犯了一个拼写错误，需要df['time'] = df['time'].dt.floor('T') 其中区别是 dt 而不是 df 介于两者之间点。
df['time'] = df['time'].dt.floor('T')
I unfortunately can't comment yet, otherwise I would've commented.
Looking at this SO question it seems you have made a typo and need df['time'] = df['time'].dt.floor('T') where the difference is the dt instead of the df in between the dots.
