我有以下代码
import pandas as pd
pd.to_datetime(pd.DataFrame(['12/4/1982']))
然而，有了这个，我得到以下错误
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.11/site-packages/pandas/core/tools/datetimes.py", line 1053, in to_datetime
result = _assemble_from_unit_mappings(arg, errors, utc)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

您能帮我了解一下我的代码出了什么问题吗？
