LombScargle not fully working

Description

What steps will reproduce the problem?

1. LS = LombScargle(t, y, normalization=‘psd’)
2. frequency, power = LS.autopower()
3. print (LS.false_alarm_probability(power.max()))

What is the expected output? What do you see instead? One number corresponding to the probability of the peak being significant should be printed. However, this is what I get instead: init() got an unexpected keyword argument ‘normalization’

And if I remove the normalization part from within the brackets, then this is what I get: ‘LombScargle’ object has no attribute ‘false_alarm_probability’

Please provide any additional information below I have astropy 3.0.2 installed and if I go to the core.py (in the lombscargle folder), the def false_alarm_probability IS inside the class LombScargle, as well as the normalization variable. Thus, I am really not sure why it isn’t recognised when I run the code.

@ccordoba12 I’ve just solved it by transferring some files to another folder. So all is gooood thanks

Hi CAM-Gerlach you were right. I was running an old version of Astropy and to run the new one, I need to install it from python 3.6. I did it and now is working perfectly 😃

Have a nice day, All the best,
