Specifically I'm interested in a safe way (i.e. no pickle) of
saving/restoring Generator state via HDF5 file storage.

Hi all,
is there a canonical way of serialising Generators (not via pickle). Would
the following be reasonable for saving and restoring state:
```
def serialize_rng(rng):
klass = rng.bit_generator.state['bit_generator']
entropy = rng.bit_generator.seed_seq.entropy
return klass, entropy

I just wanted to know how the current interpreter worked.

Thanks for everyone's help, I'll look into those links matti.

Hi all,
Let's assume we have two float arrays, `x0` and `h`, both of which have the
same shape. Let's calculate the sum of those two arrays:
```
x1 = x0 + h
```
The true representable difference between `x1` and `x0` is:
```
dx = x1 - x0
```
Is it also possible to get that exact representation

Hi all,
in the last few weeks have there been any PRs that have touched objects
that are followed by the Python ResourceTracker. I'm talking about things
like Locks, semaphores, mutexes, etc?
I'm seeing some weird behaviour in scipy CI where a test (
