我正在尝试使用https://unidata.github.io/MetPy/latest/examples/Four_Panel_Map.html#sphx-glr下载了四个面板地图py的例子来制作天气图，但我在运行这个脚本时发现了这个问题：

我认为我对xarray有一些问题，所以我尝试升级我的xarray，这样做：pip安装"；xarray[io]"；pip安装"；xarray[完成]"；但我得到了相同的ValueError。Python 3.8版有什么想法吗？提前感谢！Fede
该特定数据文件是netCDF-4格式的，zarr或scipy都不支持该格式。我很惊讶安装xarray[io]或xarray[complete]没有修复它。正在尝试手动执行pip install netcdf4。
(如果这不起作用，请在此处进行评论，并用新错误更新上面的回溯。(
