title: ModuleNotFoundError: No module named 'cv2' How can I install packages in python folders? rather than in anaconda
body: <p>I have previously installed python 3.7, anaconda3 and jupyter notebook.
  Then I tried to install opencv library using the following command.</p>
  
  <p><code>pip install opencv-python</code></p>
  
  <p>and it said,</p>
  
  <blockquote>
    <p>Requirement already satisfied: opencv-python in c:\programdata\anaconda3\lib\site-packages (4.1.1.26)</p>
  </blockquote>
  
  <p>When I tried to import open-cv library from IDLE it gives the following error.</p>
  
  <blockquote>
    <p>ModuleNotFoundError: No module named 'cv2'.</p>
  </blockquote>
  
  <p>But when I run it from the jupyter notebook it works. </p>
  
  <p>The reason for this as I see is that the packages are installed in the anaconda3 folders but not in the python folders.</p>
  
  <p>How can I install packages in python folders? As I need to run this from the IDLE.</p>
  
  <p>I'm using python 3.7.1 on windows 10.</p>
  
  <p>Thank you.</p>
