Python读取grib2文件Total precipitation显示no matches found

用python的pygrib读取grib2文件

1. import pygrib
   
2. grbs = pygrib.open('Z_SURF_C_BABJ_20210115080515_P_CMPA_FAST_CHN_0P05_DAY-PRE-2021011508.GRB2')
   
3. grbs.seek(0)
   
4. f = open('information.txt', 'w')
   
5. for grb in grbs:
   
6.     f.write(str(grb)+'\n')
   
7. f.close()

复制代码

得到1:Total precipitation:kg m-2 (instant):regular_ll:surface:level 0:fcst time 0 hrs:from 202101150800

但是

1. grbs.seek(0)
   
2. grb = grbs.select(name='Total precipitation')[0]

复制代码

提示：ValueError: no matches found
求大神指点迷津！

同求大神，个人感觉是编码不一致导致的，但是没解决

#####可以利用索引进行选取###
grbs = pygrib.open(path_nwp)
tp  =(grbs[9]).values
