swt2.py demo not working

[XareniGalindo]

Hello!

As the title of this issue says, I am trying to use swt2.py to get to know how the pywt.swt2 works to use it on my own images. However, when I run it I get the next error value:

ValueError: 'image' is not a valid value for origin; supported values are 'upper', 'lower'

Besides, when I try to use the demo presented on the home page (https://pywavelets.readthedocs.io/en/latest/index.html) on
my own data to run by adding the next code lines:

import numpy as np
import matplotlib.pyplot as plt
import pywt
import pywt.data
from PIL import Image

Load image

path = 'C:/Users/Xareni Galindo/Pictures/'
filename = '60xclose-3_w3soSPIM-561_s5-1to85-1.tif'

opening image

arr = Image.open(path + filename)

#converting images to array
arr.load()
data = np.asarray(arr)

The rest of the demo code is not changed, after running the code I get the next error message

ValueError: start_level must be less than 1.

What could be wrong? I am a newbie in coding and in the use of wavelets, so I am not sure what could be happening.

I am using PyWavelets 1.1.1 in Anaconda. my variable "data" is of type "array of uint8".

Thank you in advance

ValueError: 'image' is not a valid value for origin; supported values are 'upper', 'lower'

I can reproduce this, something got broken.

This is a matplotlib bc-break, got changed in 3.3.0 apparently. See origin docs in https://matplotlib.org/3.3.0/api/_as_gen/matplotlib.pyplot.imshow.html. I'll fix this.

'image' corresponds to 'upper', which should be used now.
