Dear all, I'm new user of python. And I wanted to do the continuous wavelet analysis of my data. But first of all, when I tried to run the following command: In[1]: import numpy as np In[2]: from scipy.signal import SDG, Morlet, cwt I got the following error messages: --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-43-e18eb7700f8b> in <module>() ----> 1 from scipy.signal import SDG, Morlet, cwt ImportError: cannot import name SDG In[3]: from scipy.signal import Morlet, cwt --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-44-2cf611117e43> in <module>() ----> 1 from scipy.signal import Morlet, cwt ImportError: cannot import name Morlet How can I solve this issues?
