我正在尝试加载 grib2 文件,但我不确定这些文件是否是问题所在,或者我尝试加载它们的方式。
这些文件是从这里提取的(我没有从这里下载它们,而是从一个从这里获取它们的同事的文件夹中复制它们 - 所以它们实际上应该是相同的文件......,但我也尝试插入ftp 地址并得到相同的错误)。
我累了pygrib
grbs = pygrib.open('pgbf2016060100.01.2016053100.grib2')
得到这个错误:
---------------------------------------------------------------------------
IOError Traceback (most recent call last)

IOError: [Errno could not open %s] pgbf2016060100.01.2016053100.grib2
我试过了xarray
ds = xr.open_dataset("pgbf2016060100.01.2016053100.grb2",engine='pynio')
我得到这个错误

我直接试了NIO
f = nio.open_file("pgbf2016060100.01.2016053100.grb2")
我得到与来自的错误相同的错误xarray
。
有什么建议吗?
