GOES rgb recipes doesn't work out of the box

[data-panda]

Hi, I am hitting a roadblock where goes_latest() returned xarray object does not contain rgb as an attribute such that the call G.rgb.TrueColor() throws exception (or any methods within the rgb.py). Am I missing something very trivial which has changed recently? Because not being able to replicate the very first few lines of the RGB demo is a bummer.

Hi @data-panda, sorry you are hitting a roadblock.

I'm not able to reproduce your problem. This is what I did...

from goes2go.data import goes_latest
import matplotlib.pyplot as plt

ds = goes_latest()

ds.rgb

rgb = ds.rgb.TrueColor()
rgb

plt.imshow(rgb)

---

That said, the rgb attribute in the statement ds.rgb.TrueColor() is an xarray Dataset accessor, which should be loaded when you import goes2go.

These lines are at the top of init.py when you import goes2go

try:
    import goes2go.accessors
except:
    warnings.warn("goes2go xarray accessors could not be imported.")

If you are getting the warning that goes2go xarray accessors could not be imported, then that would be your problem.

These are imported by the accessor; if any of these are not in your python environment, that could cause the problem

import warnings
import cartopy.crs as ccrs
import numpy as np
import xarray as xr
from shapely.geometry import Point, Polygon

Indeed the issue was with cartopy not being in the environment.
