np.ndarray description says: buffer : object exposing buffer interface It's nice that it works with mmap:
b = mmap.mmap (...) u = np.ndarray (buffer=b ...) but you wouldn't know it from the above description. It doesn't look to me that the object returned by mmap exposes the buffer interface, does it?
