PIL has no attribute ANTIATLAS warning (versioning issue ?)

[jgagneastro]

I have encountered the following problem when running this example code:

from Finder_charts import create_finder_charts, Crosshair, Survey, Target
from astropy.time import Time
import tempfile

ra, dec=0,0
pmra, pmdec=-100,100
ref_epoch = Time(2015.0, format='jyear')

create_finder_charts(ra, dec, pmra=pmra, pmdec=pmdec, ref_epoch=ref_epoch, crosshair_type=Crosshair.CROSS_NO_CENTER)

crosshair_type=Crosshair.CROSS_NO_CENTER)
A problem occurred while creating a color image for object ra=273.721554, dec=-26.914877
Traceback (most recent call last):
  File "/Users/jonathan/Documents/Python/Python_Packages/Finder_charts/Finder_charts.py", line 225, in create_color_image
    r = Image.fromarray(create_lupton_rgb(r)).convert('L').resize((xmax, ymax), Image.ANTIALIAS)

It seems like this could be caused by a version issue in PIL.

Further down the line, the code crashes with this error message:

    b, gaia_wcs, obs_coords = create_gaia_finder_chart(ra, dec, size=img_size, band='Bp', epoch=gaia_epoch)

KeyError: 'source_id'

This could also be caused by a versioning issue, which might be fixed by providing exact package version requirements in setup.py.

I think I have fixed this with a fresh reinstall of Finder_charts in a new conda environment. I am not sure why it worked out differently the first time around - I think at some point I had installed "requests" with conda after my Finder_charts installation, which might have broken something. Here is the current versions of every package I ended up with in the conda environment where my Finder_charts installation works (the only thing I did was python setup.py install from Finder_charts's current repo, and then conda install pandas for my own use in the same env) :
