Return the requested number of words for PRNG seeding.
A BitGenerator should call this method in its constructor with an appropriate n_words parameter to properly seed itself.
- n_words : int
- dtype : np.uint32 or np.uint64, optional
The size of each word. This should only be either uint32 or uint64. Strings (‘uint32’, ‘uint64’) are fine. Note that requesting uint64 will draw twice as many bits as uint32 for the same n_words. This is a convenience for BitGenerator`s that express their states as `uint64 arrays.
- state : uint32 or uint64 array, shape=(n_words,)
