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)
    514
--> 515 file_proxy = _proxy(file, 'str',
create_variable=_create_variable)
    516 setattr(file_proxy.__class__,'set_option',set_option)
    517 file_proxy.file = file

/usr/local/lib/python2.6/dist-packages/PyNIO/Nio.pyc in _proxy(obj,
*specials, **regulars)
    226 _known_proxy_classes[key] = cls
    227 # instantiate and return the needed proxy

--> 228 instance = cls(obj)
    229 return instance
    230

/usr/local/lib/python2.6/dist-packages/PyNIO/Nio.pyc in __init__(self, obj)
    167
    168 def __init__(self, obj):
--> 169 super(_Proxy, self).__init__(obj)
    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,

-Sourish
