Is there any document about how to use dynesty with pycbc_inference?

[yanyuechuixue]

my config is

[sampler]
name = dynesty
nlive = 1200
dlogz = 0.001
checkpoint-interval = 5000

However, the sampler stop too early. There is no enough points.

I have tried to decrease dlogz in [sampler] config, but it does not work.
In the output on the screen, it always says ... | dlogz: 10.085 > 1.209 no matter what dlogz is (no matter what dlogz is, the last number is always 1.209).

The version of pycbc_inference I used is 1.15.4 and 678a06.

So is there any document about how to use dynesty sampler as well as cpnest and multinest ?
I have searched with google but found nothing.

Thanks a lot!

@dfinstad @sum33it Could you write some documentation on how to use dynesty and multinest, and add it to the docs page?

@yanyuechuixue I think the issue you're seeing with the dlogz not getting any better might be a bug with the dynesty sampler. We've had other people run into the same problem; @sum33it or @ahnitz should comment, as they've been using this more. Also note: setting checkpoint interval won't do anything, as we don't have checkpointing currently enabled with dynesty. @sum33it is working on that, so we should have checkpointing enabled soon.
