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了错误。 panelda = pd.Panel()

     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)

是的，pd.Panel已经被弃用了。 - Scott Boston

Answer 1

我自己找到了答案，原来我使用的是最新版的Pandas v1.2.0，从0.25.0版本开始，Pandas模块中已经移除了panel。

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

除非你想使用xarray，否则你需要卸载并安装该版本之前的版本。

我在使用xarray=0.11.3时遇到了问题，因为需要python3.7。我的解决方案是conda uninstall pandas然后conda install -c conda-forge pandas=0.24。感谢您的帮助。 - Under-qualified NASA Intern
