errors while running pyLIMA_example_3

[XinliHao]

When I try to run pyLIMA_example_3, there are some errors occor. I didn't edit the example at all . It remained its initial appearance. I don't know why? wo can help me ? Or who met the same question with me? Thank you so much !

error position:

latitude = -27.130814, bad_weather_percentage = 10%, moon_windows_avoidance (degree)=30,

minimum_alt=30)

It seems like an Astropy issue. It seems you are using a version which might be not the latest stable, can you try downgrading to the last stable version?
