模块 'pandas' 没有属性 'Panel'

Question

我在将字典数据帧转换为面板数据帧时遇到错误

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","High","Low","Close","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'

Answer 1

自己找到了答案，我使用的是最新的 Pandas v1.2.0，其中的面板已从 Pandas 模块 0.25.0 开始移除。

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，否则您需要卸载并安装之前的版本。
