Astropy python error

Any idea on this one?

Yeah, this needs to be dealt with.

The core of the error seems to be in /usr/lib/python2.7/dist-packages/astropy/io/fits/hdu/image.py - meaning it's in the astropy package, and I believe the problem manifests itself due to an incompatibility with the installed version of python numpy package.

This issue is probably relevant and probably deals with the same problem: https://github.com/matthewearl/faceswap/issues/5

I'll have to see what would be the best way to solve this problem.

As a temporary workaround, if your software has a setting for it, please try uploading the image either as JPEG or PNG. FITS format conversion with astropy is the issue.

I'm trying to test in SGP, but there is no option for this. Do you know of another application that I can quickly do solve tests with? Thanks!

[Jusas]

You can try Ansvr, which uses a cygwin build of astrometry.net.

Unfortunately I haven't had the time to dig into this for the last few days but this issue is still on the top of my priority list.

Sorry I wasn't more clear. I'm trying to test solves in sequence generator pro pointed at Astrometry Api Lite, but it doesn't upload in JPG. Do you know of one other than Ekos that will upload in JPG for testing?

Cheers

This is an issue whether or not I use a JPG upload option.

This should be fixed in HEAD, but I've not created a new release yet - still need to test emerged data corruption issue fixes with sqlite, as soon as I'm fairly confident that the fixes work I'll make a new release.
