Python Can'；t将对象数据类型转换为日期时间格式

我想将一列转换为DateTime格式，并将日期和时间分开。我已经得到了日期时间转换的解决方案 和代码：

df2['date']=pd.to_datetime(df2['date'].astype(str), format='%Y%m%d%H%M',errors='coerce')

但是，每当我尝试查看df2['date']的数据类型时，该列仍然是一个对象数据类型。 当我尝试使用代码将其分离时：

df2['date'], df2['Time'] = df2['date'].dt.normalize(), df['date'].dt.time

这给了我一个错误：

AttributeError: 'DataFrame' object has no attribute 'dt'

打印df2.2列时，输出为

列中有

多索引

，因此对于选定列，需要元组：

df2[('date', 'GMT')] = df2[('date', 'GMT')].dt.normalize()
df2[('Time', 'GMT')] = df2[('date', 'GMT')].dt.time

---

它仍然给我同样的错误：

AttributeError:'DataFrame'对象没有属性“dt”

@MalaPokhrel-什么是

print（df2.columns）

？
