python - 属性错误 : 'Timestamp' object has no attribute 'timestamp

Question

在将 panda 对象转换为时间戳时，我遇到了这个奇怪的问题。

Train['date'] 值类似于 01/05/2014，我正在尝试将其转换为 linuxtimestamp。

我的代码:

Train = pd.read_csv("data.tsv", sep='\t') # use TAB as column separator
Train['timestamp'] = pd.to_datetime(Train['date']).apply(lambda a: a.timestamp())

我得到这个错误:

Traceback (most recent call last):
  File "socratis.py", line 11, in <module>
    Train['timestamp'] = pd.to_datetime(Train['date']).apply(lambda a: a.timestamp())
  File "/home/ubuntu/.local/lib/python2.7/site-packages/pandas/core/series.py", line 2220, in apply
    mapped = lib.map_infer(values, f, convert=convert_dtype)
  File "pandas/src/inference.pyx", line 1088, in pandas.lib.map_infer (pandas/lib.c:62658)
  File "socratis.py", line 11, in <lambda>
    Train['timestamp'] = pd.to_datetime(Train['date']).apply(lambda a: a.timestamp())
AttributeError: 'Timestamp' object has no attribute 'timestamp'

Answer 1

to_datetime seems to be deprecated.请改用 to_pydatetime()...
