Python scipy find_peaks return empty
Question:
I try to find peaks of below array using the scipy find_peaks function.
Array = np.array([84.6345, 84.643, 84.6375, 84.568, 84.524, 84.5345, 84.5305, 84.548, 84.562, 84.6295, 84.668, 84.5795, 84.565, 84.5715])
peaks = find_peaks(Array)
But I got returned result with empty peak as below.
(array([ 1, 5, 10], dtype=int64), {})
Any advice or guidance on this would be greatly appreciated, Thanks.
Answers:
Your peaks are at elements 1, 5, and 10. What are you looking for? Do you want the actual values? That would be Array[peaks[0]].
The second return value only contains entries for specific argument combinations.
