title: How to upgrade OpenCV in Anaconda (windows)?
body: <p>everyone.</p>
  <p>My problem is that I need the last version of OpenCV (4.3.0) to run a code but when I checked my version of opencv with the line:</p>
  <pre><code>print(cv2.__version__)
  </code></pre>
  <p>it said that my version of cv2 is the 3.4.2. So I went into my anaconda, environment, I marked opencv for upgrade, but it seems it is the last version it can install. So I tried a command in the cmd.prompt of anaconda :</p>
  <pre><code>pip install --upgrade opencv-python==4.3.0.36
  </code></pre>
  <p>And then, when I checked &quot;opencv&quot; in the installed modules of my anaconda environment, I saw two opencv. One is &quot;opencv&quot; version 3.4.2, and then, just below, there is &quot;opencv-pyton&quot; version 4.3.0. BUT, when I checked again my version of cv2 with &quot;print(cv2.<strong>version</strong>)&quot;, it was still telling me that my version is 3.4.2 (I also tried to uninstall the opencv 3.4.2 to see if anaconda would then take into account the opencv-pyton 4.3.0 but no, it gives me an error).</p>
  <p>Does anyone have an idea how to upgrade my version of opencv with anaconda ? Thanks everyone.</p>
