FYI: install_requires in setup.py is missing packages

[paulmueller]

I just installed version 0.2.1 from pypi and it wouldn't import, because some packages were not installed automatically.
These were pywcs, FITS_tools, and astropy. I see that astropy is already a dependency in master.

Thanks @paulmueller. pywcs is not required, and is actually deprecated, but astropy is. FITS_tools is a soft requirement, and it is included in the REQUIREMENTS file, but apparently that isn't acknowledged by PIP. Ideally, I want to switch from using FITS_tools to reproject, but I haven't had time to make that switch yet, so I'll leave this issue open as a reminder to do so.

Hi keflavich. I encountered the same error and doing a pip install pysetup fixed the issue. The next problem that showed up is as follows:

---

ImportError Traceback (most recent call last)

----> 1 import image_registration as imreg

c:\users\jerome\miniconda3\envs\py27\lib\site-packages\image_registration_init_.py in ()
----> 1 from cross_correlation_shifts import cross_correlation_shifts, cross_correlation_shifts_FITS

3 from register_images import register_images
4 import fft_tools
5 import tests

c:\users\jerome\miniconda3\envs\py27\lib\site-packages\image_registration\cross_correlation_shifts.py in ()
2 from AG_fft_tools import correlate2d,fast_ffts
3 except ImportError:
----> 4 from image_registration.fft_tools import correlate2d,fast_ffts
5 import warnings
6 import numpy as np

ImportError: cannot import name fast_ffts

Can you help me fix this issue?

@jpdeleon There were some outdated imports. I just fixed them. Try the latest version.
