Describe the bug I am getting an unfamiliar error: Ellipsoid check failed q=0, 401.82077270563605 What is this about?
Setup I am running the following dynesty setup: dsampler = dynesty.DynamicNestedSampler(loglike, prior_transform, ndim,nlive=10000)
Dynesty output

Thank you!
Could you try 2.1.3 please, I fixed an issue like that earlier: https://github.com/joshspeagle/dynesty/blob/master/CHANGELOG.md#213---2023-10-04
Thank you! That indeed fixed it -- the run went smoothly.
