在跑步的时候：

df.to_feather(file_path)

发生以下错误：

Traceback (most recent call last):
  File "X:\FAKE\script.py", line 37, in df_to_feather
    df.to_feather(file_path)
  File "X:\FAKE\venv\lib\site-packages\pandas\util\_decorators.py", line 214, in wrapper

  File "pyarrow\error.pxi", line 105, in pyarrow.lib.check_status

任何想法如何解决这个问题将不胜感激。:)

最后一行：

pyarrow.lib.ArrowNotImplementedError: extension<pandas.period>

告诉你数据类型pandas.Period目前没有为羽毛格式实现。它是一列或您的索引。您可以尝试使用方法将其转换为期间的开始/结束.asfreq()，也可以使用该.to_timestamp()方法将其转换为时间戳。
