I don't get this error with the current desc-stack-weekly

heather999 commented 2 years ago

@wmwv This is a warning due to how cfitsio checks its version - apparently a rounding error. So an upstream, non-fatal issue. Noted by the DM folks on Slack, and in the healpy repo.
I don't see that there is a definitive fix available - perhaps when healpy patches the cfitsio version checking and rubin-env updates to that version of healpy, this warning will disappear - though reading the Slack thread, it wasn't clear which package(s) were causing those warning messages. In the meantime, I think it's safe to ignore.

You won't see this in desc-stack-weekly, since that's an older version of the stack (and something I hope to upgrade this week) and older versions of the dependencies.

Thanks, @heather999 The idea that a rounding error is involved is mildly terrifying. Versions are not floats and I'm deeply worried about anything that treats them that way. I appreciate that you're on top of it and tracking the issue.

@rknop I see what you're saying now that 4.000999999... = 4.001 which is still different than 4.01

Closing - we understand the issue, I believe we are still waiting for a fix upstream from us.
