from cinrad.io import PUP 这一句可以正常执行 f=PUP('Z_20200727094405Z_CAPPI_00_110') 执行一句时总是报错， 在python3.7 python3.8 都试了

报错信息如下： raise MaxRetryError(_pool, url, error or ResponseError(cause)) urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='raw.githubusercontent.com', port=443): M ax retries exceeded with url: /Unidata/MetPy/v0.12.1/staticdata/sfstns.tbl (Caused by NewConnectionE rror('<urllib3.connection.HTTPSConnection object at 0x0000000014F19248>: Failed to establish a new c onnection: [Errno 11004] getaddrinfo failed'))

During handling of the above exception, another exception occurred:

请问是数据文件格式不对，还是没有安装好？

[CyanideCN]

模块是用的metpy来解PUP文件，在第一次解码的时候metpy会下载一些数据到本地，如果网络不好的话就会出现这个问题

[CyanideCN]

而且你这个数据好像是新版的PUP数据，CAPPI产品目前还不支持读取

多谢，按照 https://www.cnblogs.com/zuoanfengxi/p/12724698.html 这个方法解决了网络下载问题；文件还是打不开，像你说的，文件格式好像是新格式。
