我尝试将这两个返回值重命名为相同的名称，但仍然没有效果。

How do I fix this error?

I tried renaming the two returns to the same name, but it is still not working.

从你的错误信息来看，log_returns15 是一个 Pandas Series，它具有用于计算相关性的 [corr](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.corr.html) 方法。[corrwith](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.corrwith.html) 是一个 Pandas DataFrame 方法，不能在 Series 对象上调用。
所以，要么使用 corr，要么将 log_returns15 转换为 DataFrame。
英文:
from your error it looks like log_returns15 is a Pandas Series, which has a [corr](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.corr.html) method for correlations. [corrwith](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.corrwith.html) is a Pandas DataFrame method, which can not be called on a Series object.
So, either use corr or make log_returns15 a DataFrame.
