ptemcee incompatible with numpy 1.23.0
As a heads up, over on pyfstat we've just seen that ptemcee now seems to have become incompatible with the latest numpy 1.23.0 release of June 23, failing with index errors when computing acf: https://github.com/PyFstat/PyFstat/issues/403
Looking at the latest bilby CI runs, it seems you're still pulling in numpy 1.22.4 and hence haven't been hit yet, but I don't see a pin for that in the requirements, so maybe it's just gitlab CI being less aggressive in downloading recent releases than github.
Anyway, I remember some rumours that bilby devs were considering helping out with ptemcee maintenance, is there still hope of that happening?
