ValueError: Sample sequence X is empty

I'm tried to run whereami learn -l test_location -n 100 and get following error:

I am assuming that there were no access points nearby? I tried to add a check for this in the code. Are you sure your wifi was switched on? (just checking)

[drakmail]

Yes, I was connected to wifi AP and there was several (about 15) another access points

[drakmail]

Hm, seems that I found reason - I'm was turned on WiFi hotspot. It perfect work with wifi hotspot turned off

@drakmail thanks for the update! Glad it was resolved.
