如何删除DataFrame中的连续/连续/相邻重复项？

我正在处理CSV格式的数据，按日期排序，然后按标识号排序。标识号可以在不同的日期出现，但是我只想删除每日重复的记录。drop_duplicates会留下一个唯一的实例，但随后所有其他日子都将其删除。我已经尝试过了，但是得到了错误：

localhost:~/Desktop/Public$ python3 test.py 
Traceback (most recent call last):
  File "test.py", line 31, in <module>
    df2.loc[df2.shift(1) != df2]
  File "/usr/lib/python3/dist-packages/pandas/core/indexing.py", line 1028, in __getitem__
    return self._getitem_axis(key, axis=0)
  File "/usr/lib/python3/dist-packages/pandas/core/indexing.py", line 1148, in _getitem_axis
    raise ValueError('Cannot index with multidimensional key')
ValueError: Cannot index with multidimensional key

编辑原始帖子以添加：

我尝试index_reset（）删除任何多索引。这是数据集的示例：
