Hi sir,
I am working on Time frequency decomposition methods and tried to implement your paper, But during execution i am getting an error: 'ZipFile' object is not callable.......kindly help me sir

for kk,ind in zip(f,range(len(f))):
f[kk] = f[kk] - np.mean(f[kk])
b, a = signal.butter(4, paramsData[dBase]["LPcutoff"] / (0.5 * Fs), btype='low', analog=False)
f[kk] = signal.filtfilt(b, a, f[kk])
