This is no documentation or any source code for ndim attribute. u

Use:

len(v.shape)

@dnadeau4 it seems in the example below, it inherits numpy behavior.. Might be good to document this

In [1]: import numpy as np
In [2]: import cdms2 as cdm
In [5]: npVar = np.ones([10,10])
In [6]: cdVar = cdm.createVariable(npVar,id='cdVar')
In [7]: npVar.ndim
Out[7]: 2
In [8]: cdVar.ndim
Out[8]: 2
