Use Astropy instead of PyFITS and PyWCS #6

Closed astrofrog closed 11 years ago

astrofrog commented 11 years ago

Since Ginga is now listed as an affiliated package for Astropy (http://affiliated.astropy.org/), I think the pyfits/pywcs dependencies should be changed to Astropy.

That's definitely a good idea - hopefully it will also open other opportunities to make integration with Astropy easier.

ejeschke commented 11 years ago

This is a good suggestion. Look for it in the next few commits.

eteq commented 11 years ago

FYI, @ejeschke , if you don't know about the feature, if you added Closes #6 in a commit message, it will automatically close this issue and make a not that you fixed it in that commit.

I'm trying to get #10 to work and ran into this issue (i.e. ImportError for pyfits because I only have astropy installed). @ejeschke Can you make the change to astropy? If you don't have time, let me know and I can do it.

ejeschke commented 11 years ago

@cdeil, the change to use AstroPy is coming soon. I plan to try to import from AstroPy first, then "fall back" to individual imports from pyfits and pywcs if AstroPy is not installed.

Trying to build AstroPy 0.2.1 I get these errors:

python3 build is ok

cdeil commented 11 years ago

I've also seen this error on Ubuntu. Running sudo apt-get install python-pip first resolved the issue for me. @astrofrog @eteq Should we file an issue with astropy for this? I could try to add a travis build to the build matrix that shows this problem.

ejeschke commented 11 years ago

@cdeil, could you check out the latest commit? It works with AstroPy under python3. I don't have a working AstroPy under python2 to test, so I'd like to hear the result before I close this issue.

ejeschke commented 11 years ago

ok, just saw your message about installing pip. Works a charm and I have verified that astropy changes work for me under python 2 and 3 on Ubuntu 12.

cdeil commented 11 years ago

Works for me. Thanks!

ejeschke commented 11 years ago

ok, closing this issue.
