## 解决问题 ##

"Passing list-likes to .loc or \[\] with any missing labels "  
KeyError: "Passing list-likes to .loc or \[\] with any missing labels is no longer supported. The following labels were missing: Index(\['Item\_Identifier'\], dtype='object'). See https://pandas.pydata.org/pandas-docs/stable/user\_guide/indexing.html\#deprecate-loc-reindex-listlike"

## 解决思路 ##

“将列表like传递给.loc或\[\]，且没有任何标签”  
KeyError: "不再支持将列表类型传递给.loc或\[\]，且不支持任何缺失的标签。以下标签缺失:Index(\['Item\_Identifier'\]， dtype='object')。

## 解决方法 ##

在执行loc函数的时候，数据集中不存在指定的字段，请重新查看当前的字段是否被删除或者重命名，亦或者根本没有该字段！
