welch() got an unexpected keyword argument 'average'

Hi,

Using following code to generate sample ECG data and compute HRV metrics but running into below issue. Any help is much appreciated.

Generate 15 seconds of ECG signal (recorded at 250 samples/second)

ecg = nk.ecg_simulate(duration=15, sampling_rate=250, heart_rate=70)

Find peaks

peaks, info = nk.ecg_peaks(ecg, sampling_rate=250)

Compute HRV indices

nk.hrv(peaks, sampling_rate=250, show=True)

---
