写在最前面
尝试2019华为杯E题，但是报错：
ValueError: unrecognized engine netcdf4 must be one of: [‘store’]
Output is truncated. View as a scrollable element or open in a text editor. Adjust cell output settings…
最终解决
报错1：ValueError: found the following matches with the input file in xarray’s IO backends: [‘netcdf4’, ‘h5netcdf’]. But their dependencies may not be installed, see:
https://docs.xarray.dev/en/stable/user-guide/io.html
https://docs.xarray.dev/en/stable/getting-started-guide/installing.html
参考：https://blog.csdn.net/linxi4165/article/details/118470843
conda install xarray
注意：Python最好3.9以上
下载链接：
https://pypi.tuna.tsinghua.edu.cn/simple/netcdf4/
下载与系统对应的netCAD4，一定要注意32位还是64位，以及操作系统的类型。
找到python对应版本的
Ctrl+F进行网页搜索
该文件放到开始conda环境的cmd目录下
在pip>后输入
pip install -i https://pypi.tuna.tsinghua.edu.cn/simplenetCDF4-1.5.4-cp39-cp39-win_amd64.whl
加粗部分自行替代成自己下载版本的名字，也就是下载的WHL文件的全名之后等待安装即可。
报错二：ValueError: unrecognized engine netcdf4 must be one of: [‘store’] Output is truncated. View as a scrollable element or open in a text editor. Adjust cell output settings…
