When trying to use YASA to perform single-channel sleep spindles detection(with the sample data of yasa), after'sp = yasa.spindles_detect(data, sf)', it return nonetype:

So weird this happened again. And again when I run this I have no problems, spindles are detected.

I ran the following code on Windows with yasa 0.6.2, mne 1.2.2, numpy 1.23.5, and Python 3.10.6.

import numpy as np
import yasa
sf = 200
data = np.loadtxt('./data_N2_spindles_15sec_200Hz.txt')
sp = yasa.spindles_detect(data, sf)

@meniua are you using the same versions? If not could you try that?

[meniua]

I ran the code on Windows with yasa 0.6.2, mne 1.2.2, numpy 1.21.5,and Python 3.9.15(The highest version allowed by the Anaconda environment)，is the numpy 1.23.5, and Python 3.10.6 necessary?

[remrama]

Not sure... Changing those would definitely be worth trying, I'm not sure where else to look right now. In the meantime I'd say keep an eye on a similar thread #102 where the same problem is being troubleshooted.
