I was using this to reset the generator, in order to repeat the same sequence again for testing purposes. On Wed, Jun 24, 2020 at 6:40 PM Robert Kern <robert.kern@gmail.com> wrote:

Consider the following:
from numpy.random import default_rng rs = default_rng()
Now how do I re-seed the generator? I thought perhaps rs.bit_generator.seed(), but there is no such attribute.
In general, reseeding an existing generator instance is not a good practice. What effect are you trying to accomplish? I assume that you are asking this because you are currently using `RandomState.seed()`. In what circumstances?
The raw `bit_generator.state` property *can* be assigned to, in order to support some advanced use cases (mostly involving de/serialization and similar kinds of meta-programming tasks). It's also been helpful for me to construct worst-case scenarios for testing parallel streams. But it quite deliberately bypasses the notion of deriving the state from a human-friendly seed number.
