模块“熊猫”没有属性“面板”

问题描述

我在将字典数据框转换为面板数据框时出错

panelda = pd.Panel()

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-33-e8e84d2172b7> in <module>
     11     panaldata[ticker] = panaldata[ticker][["Open","High","Low","Close","Volume"]]
     12     #print(panaldata[ticker].head())
---> 13 panelda = pd.Panel()
     14 #panelda.minor_axis = ["Open","Volume"]
     15 #panelda.major_axis = panel.major_axis.tz_localize(pytz.ist)

c:\miniconda\lib\site-packages\pandas\__init__.py in __getattr__(name)
    242         return _SparseArray
    243 
--> 244     raise AttributeError(f"module 'pandas' has no attribute '{name}'")
    245 
    246 

AttributeError: module 'pandas' has no attribute 'Panel'

解决方法

我自己找到了答案，我使用的是最新的 Pandas v1.2.0，该面板已从 Pandas 模块 0.25.0 中删除。

print(pd.__version__)
print(np.__version__)
1.2.0
1.19.4

来自 0.25.0 / 1.2.0 发行说明

Warning: The panel has been fully removed. For N-D labeled data structures,please use xarray

除非您想使用xarray，否则您需要先卸载并安装该版本。
