netcdf 创建变量：错误需要整数

Question

我的代码：

data = Dataset('/scratch/uni/ifmto/janniklas/data.nc', 'w', format='NETCDF4_CLASSIC')

data.createDimension('z', len(zn))
data.createDimension('x', len(xn))
data.createDimension('y', len(yn))

nz = data.createVariable('zn', np.float32, 'z')
nx = data.createVariable('xn', np.float32, 'x')
nx = data.createVariable('yn', np.float32, 'y')

N = data.createVariable('N', np.float32, 'z','x','y')

一些附加信息：

shape(nx) = 288 ; shape(ny) = 288 ; shape(nz) = 67
shape(N) = (67,288,288)

nx, ny 和 nz 必须是维度向量

我收到以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Aufgabe.py", line 97, in <module>
    N = data.createVariable('N', np.float32, 'z','x','y')
  File "netCDF4/_netCDF4.pyx", line 2222, in netCDF4._netCDF4.Dataset.createVariable (netCDF4/_netCDF4.c:16460)
  File "netCDF4/_netCDF4.pyx", line 3141, in netCDF4._netCDF4.Variable.__init__ (netCDF4/_netCDF4.c:27788)
TypeError: an integer is required

我正在使用 python 2.7

当您设置变量的维度时，您必须使用 tuple 而不仅仅是序列：

from netCDF4 import Dataset
import numpy as np

data = Dataset('data.nc', 'w', format='NETCDF4_CLASSIC')

data.createDimension('z', 67)
data.createDimension('x', 288)
data.createDimension('y', 288)
# 'z' has to be a tuple
nz = data.createVariable('zn', np.float32, ('z',))
nx = data.createVariable('xn', np.float32, ('x',))
nx = data.createVariable('yn', np.float32, ('y',))

N = data.createVariable('N', np.float32, ('z','x','y'))
