How to define a function using cwt in Python

I am trying to define a function using cwt in Python, however, I get the error message
global name 'cwt' is not defined
This is the code that I am using:
import os
import matplotlib.pyplot as plt
from matplotlib import cm
from matplotlib.pyplot import specgram
import librosa
import librosa.display
import numpy as np
from ssqueezepy import cwt
from ssqueezepy.visuals import plot, imshow
from numba import jit
#jit
def scaleogram_convert(data):
Wx, scales = cwt(data, 'morlet')
Wx = abs(Wx) # remove complex component
return Wx
img3 = scaleogram_convert(trimmed)
How can I get this function to work correctly when called?
Any help is greatly appreciated!

Getting Error with "from_raster" attribute in pysheds

This is my first time asking a question. I am trying to use "pysheds" to analyze some hydrologic DEM files. The developer as some pretty thorough "how to" videos but when I try to load the DEM file in the way that they show I get the following error:
module 'pysheds.grid' has no attribute 'from_raster'
here's my code
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors as colors
import geopandas as gpd
import pysheds
import pysheds.grid as Grid
import mplleaflet
grid = Grid.from_raster('path.tif', data_name = 'dem')`
I checked the print(dir(Grid)) in the console and didn't see this attribute listed.
Am I missing something?
Thanks!

According to documentation, you should import Grid from pysheds.grid like this:
from pysheds.grid import Grid
grid = Grid.from_raster('n30w100_con', data_name='dem')
grid.read_raster('n30w100_dir', data_name='dir')
grid.view('dem')
instead of
import pysheds.grid as Grid

Matplotlib FuncAnimation not plotting any chart inside Jupyter Notebook

Simple matplotlib plot. Here is my code
from matplotlib import pyplot as plt
from matplotlib.animation import FuncAnimation
from itertools import count
import random
x = []
y = []
index=count()
def animate(i):
x.append(next(index))
y.append(random.randint(0,10))
plt.plot(x,y)
a = FuncAnimation(plt.gcf(),animate,interval=1000)
plt.tight_layout()
plt.show()
Running the code above I get
<Figure size 576x396 with 0 Axes>
but no chart appears.

Are you using Jupyter notebooks to run it? I tried with native libraries and it works just fine. The plots are visible.
Checking here i see the same situation. Could you try to use %matplotlib inline before importing matplotlib as:
%matplotlib inline # this line before importing matplotlib
from matplotlib import pyplot as plt
That said, the animation can be displayed using JavaScript. This is similar to the ani.to_html5() solution, except that it does not require any video codecs.
from IPython.display import HTML
HTML(a.to_jshtml())

AttributeError: 'module' object has no attribute 'save' - matplotlib

I get this error when I try to save my plot with matplotlib ( plt.save('static/chart.png')). I am sure there is a problem with import but I am not sure what exactly. These are imports I use:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

There is no save function in matplotlib.pyplot. ׁPerhaps you want to use savefig?

Python "'module' object is not callable"

I'm trying to make a plot:
from matplotlib import *
import sys
from pylab import *
f = figure ( figsize =(7,7) )
But I get this error when I try to execute it:
File "mratio.py", line 24, in <module>
f = figure( figsize=(7,7) )
TypeError: 'module' object is not callable
I have run a similar script before, and I think I've imported all the relevant modules.

The figure is a module provided by matplotlib.
You can read more about it in the Matplotlib documentation
I think what you want is matplotlib.figure.Figure (the class, rather than the module)
It's documented here
from matplotlib import *
import sys
from pylab import *
f = figure.Figure( figsize =(7,7) )
or
from matplotlib import figure
f = figure.Figure( figsize =(7,7) )
or
from matplotlib.figure import Figure
f = Figure( figsize =(7,7) )
or to get pylab to work without conflicting with matplotlib:
from matplotlib import *
import sys
import pylab as pl
f = pl.figure( figsize =(7,7) )

You need to do:
matplotlib.figure.Figure
Here,
matplotlib.figure is a package (module), and `Figure` is the method
Reference here.
So you would have to call it like this:
f = figure.Figure(figsize=(7,7))

To prevent future errors regarding matplotlib.pyplot, try doing this:
import matplotlib.pyplot as plt
If you use Jupyter notebooks and use: %matplotlib inline, make sure that the "%matplotlib inline FOLLOWS the import matplotlib.pyplot as plt
Karthikr's answer works but might not eliminate errors in other lines of code related to the pyplot module.
Happy coding!!

Instead of
from matplotlib import *
use
import matplotlib.pyplot as plt

For Jupyter notebook I solved this issue by importig matplotlib.pyplot instead.
import matplotlib.pyplot as plt
%matplotlib notebook
Making plots with f = plt.figure() now works.

Wrong Library:
import matplotlib as plt
plt.figure(figsize=(7, 7))
TypeError: 'module' object is not callable
But
Correct Library:
import matplotlib.pyplot as plt
plt.figure(figsize=(7, 7))
Above code worked for me for the same error.
