[ncl-install] Nio.open_file problem : object.__init__() takes no parameters

[Sourish Basu]

Hi All,

    Recently, I installed NCL and PyNIO on Ubuntu 9.10 (x86_64). The 
install went smoothly, but when I try to actually use Nio to read a 
NetCDF4 file, I get the following error:

[13]: fid = Nio.open_file("SampleNetCDF.nc4",'r')
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/home/i/ResearchCode/Cost function/<ipython console> in <module>()

/usr/local/lib/python2.6/dist-packages/PyNIO/Nio.pyc in 
open_file(filename, mode, options, history, format)
    513     file = _Nio.open_file(filename,mode,options,history,format)

create_variable=_create_variable)

    517     file_proxy.file = file

*specials, **regulars)
    226         _known_proxy_classes[key] = cls
    227     # instantiate and return the needed proxy

--> 228     instance = cls(obj)
    229     return instance

    170         super(_Proxy,self).__setattr__('_obj', obj)
    171         super(_Proxy,self).__setattr__('attributes',{})

TypeError: object.__init__() takes no parameters

I'm not sure which mailing list would be appropriate to ask for help, 
but I think this is an installation issue. Has anyone seen this before?

Thanks,
