Python:KeyError:分析多个 netCDF 文件时 u'key'

Question

我对 Python 比较陌生，正在尝试分析 netCDF 文件的整个文件夹。当我尝试运行代码时，出现关键错误:u'satcode'。这是我的代码:

import netCDF4 as nc
import glob
import numpy as np

filenames = []
for name in glob.glob("/Users/my_name/Desktop/ISCCP/*"):
  print name
  filenames.append(name)
# below reads multiple files (file_list)
f = nc.MFDataset(filenames)

我知道错误出在 f = nc.MFDataset(filenames)，但我不知道为什么。我的回溯说:

runfile('/Users/my_name/.spyder/West_Coast_Model.py', wdir='/Users/my_name/.spyder') /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGG.v01r00.GLOBAL.1983.07.01.0000.GPC.10KM.CS00.EA1.00 (5).nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.0300.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.0600.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.0900.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.1200.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.1500.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.1800.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.2100.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.08.99.0000.GPC.10KM.CS00.EA1.00.nc Traceback (most recent call last):

Answer 1

我想我已经解决了这个问题。文件中的第 0 项已损坏，因此我重新下载它并将其转换为 netCDF4_CLASSIC 并且它有效。
