I was trying to apply discrete wavelet transform on 2D matrix of size (23x7680) but I get this error ValueError: Input array has fewer dimensions than the specified axes.

Any help would be appreciated.

code:

data=np.random.rand(23,7680)
coeffs = pywt.dwt2(data, 'haar')
cA, (cH, cV, cD) = coeffs

The identical code works for me. – Jussi Nurminen Sep 28 '20 at 13:01
@JussiNurminen when I am working on my data I get the above error I don't know why – Edayildiz Sep 28 '20 at 13:10
Are you sure? Also, what's your version of PyWaveLets? – Jussi Nurminen Sep 28 '20 at 13:15
@JussiNurminen yes I am sure. version (1.16.5) – Edayildiz Sep 28 '20 at 13:20
At least with 1.19.1 I don't get this problem. So maybe try to upgrade? – Jussi Nurminen Sep 28 '20 at 13:21
@JussiNurminen Also working with me when I run the above code on version (1.16.5) but when i work on my dataset i get the above error. I don't know why – Edayildiz Sep 28 '20 at 13:29
