An (instance of) ndarray doesn't have a __dict__ attribute, as you've
The class ndarray does have one.
Is it because the class ndarray doesn't have an init method ? Dunno. Robert
mentions it could be C related.
Note that float(3), dict(a=3), list() don't have __dict__ attributes
either, when float, dict, and list do have one.
You can still access the list of attributes an instance by dir, and a specific
one by __getattribute__
for k in dir(obj): print k, obj.__getattr__(k)
Or try to access the class of the instance to get the __dict__
for k in obj.__class__.__dict__.keys(): print k
