在项目中，“房屋”是源数据，其中包含多个dtype，例如“ float / int”，“ object”。
使用houses.dtypes方法，我们得到了：
Order int64
PID int64
MS SubClass int64
MS Zoning object
Lot Frontage float64
Lot Area int64
Street object
... ...
实际上，我想在“房屋”中找到数字列，因此我使用了以下代码：
houses_numeric = houses[(houses.dtypes=='int64')|(houses.dtypes=='float64')]
最后，我得到了IndexError：
IndexingError Traceback (most recent call last)
<ipython-input-50-33e1ea213da1> in <module>()
----> 1 houses_numeric = houses[(houses.dtypes=='int64')|(houses.dtypes=='float64')]
2 #(houses.dtypes=='int64')|(houses.dtypes=='float64')
3 #houses[(houses.dtypes=='int64')|(houses.dtypes=='float64')]

是否有任何修复此错误的提示？谢谢！
