title: AttributeError: module 'skimage' has no attribute 'filters'
body: <p>I have the following code:</p>
  <pre><code>import cv2
  import numpy as np
  from PIL import Image
  import skimage
  
  my_image = cv2.imread('my_image.jpeg', 1)
  
  gray = cv2.cvtColor(my_image, cv2.COLOR_BGR2GRAY)
  b = skimage.filters.threshold_local(gray,19,offset=10)
  b = Image.fromarray(b)
  b = b.convert(&quot;L&quot;)
  b.save('adaptive_output.png')
  </code></pre>
  <p>But I receive the following error:</p>
  <pre><code>b = skimage.filters.threshold_local(gray,19,offset=10)
  AttributeError: module 'skimage' has no attribute 'filters'
  </code></pre>
  <p>I am using Python 3.8 and the scikit-image version on my system is 0.18.1. I also tried the code in different IDE's but received the error everywhere.
  I have also checked <a href="https://stackoverflow.com/questions/48216075/importerror-no-module-named-filters">question 1</a>, <a href="https://stackoverflow.com/questions/23248017/cannot-find-reference-xxx-in-init-py-python-pycharm">question 2</a> and <a href="https://stackoverflow.com/questions/20479696/pycharm-unresolved-reference-error-on-the-ide-when-opening-a-working-project">question 3</a> but none of their answers worked.</p>
