This may be user error, but the following code:

#!/usr/bin/env python3

from datetime import date, datetime, timezone, timedelta
from skyfield import api, almanac
from skyfield.api import utc

ts = api.load.timescale()
e = api.load('de421.bsp')

current_time    = datetime(2019, 2, 6, 12, 25, 39)
ten_minutes_out = datetime(2019, 2, 6, 12, 35, 59)

current_time    = current_time.replace(tzinfo=utc)
ten_minutes_out = ten_minutes_out.replace(tzinfo=utc)

current_time_ts    = ts.utc(current_time)
ten_minutes_out_ts = ts.utc(ten_minutes_out)

position = api.Topos(latitude_degrees=33.7490987, longitude_degrees=-84.3901849)  # Atlanta
times, sunrise_labels = almanac.find_discrete(current_time_ts, ten_minutes_out_ts, almanac.sunrise_sunset(e, position))

results in this:

Traceback (most recent call last):

    return ufunc.reduce(obj, axis, dtype, out, **passkwargs)
ValueError: zero-size array to reduction operation minimum which has no identity

(The sun actually set in Atlanta between current_time and ten_minutes_out UTC.)

I'm not an astronomer, but I did try to trace through it a bit. It appears to break in _correct_for_light_travel_time. As far as I can tell, target and observer are reasonable-looking things (Segment 'de421.bsp' 0 SOLAR SYSTEM BARYCENTER -> 10 SUN and <Barycentric position and velocity at date t center=0 target=<object object at 0x1081e57c0>>), but for some reason, tposition and cposition end up being empty arrays ([]) and so distance and things downstream end up being empty arrays too.

At that point, I figured it would be more meaningful to report here. Will try to keep debugging.

Minimally, it seems like length_of in functions.py should verify that the vector passed in is non-empty or something, but there's probably more going on here that I'm not fully understanding.

I modeled usage off of the documentation here: https://rhodesmill.org/skyfield/almanac.html#sunrise-and-sunset

but it's possible I missed a step. I noticed other places in the documentation added planets['earth'] to the value returned by api.Topos, but couldn't figure out which was more correct.

Thanks!

Thanks for letting me know! The fix will come out in the next version.

That didn't seem to do it for the code I posted above. Now I get the following backtrace:

Happy to create a new issue if you expect this is unrelated to the previous issue.

That looks like an internal numpy error, since numpy is calling its own routines over and over without Skyfield code being mentioned again in the traceback? I'm able to run your code without any problem; adding:

print(times)
print(sunrise_labels)

to the end gives:

<Time tt=[ 2458521.02193507]>
[ True]

I'm using numpy 1.11.3. What version are you using?

I'm using numpy 1.16.1. Will downgrade and check.

I assumed it was skyfield related because it broke on the same line (within skyfield) as the previous report, but you're right, I should have started by ruling out there being a bug in numpy. Sorry about that.

Sorry, I can't reproduce this anymore. Even re-installing numpy 1.16.1 appears to work now. I must have had something incorrect in my setup affecting things.

I'm curious what was incorrect, so I'll keep looking into that, but I think this issue is safe to close out. Thanks for all your help!

It's always frustrating when errors disappear mysteriously, but I'm glad things are working for you again!
