Missing Widgets
<p>I have recently installed Orange Data Mining tool, but cannot seem to find a few widgets such as "Scatter Plot" and "Distributions". I'm currently using version 3.3.8.</p>

<p>How do I fix this issue?</p>

<p>How did you install Orange? Seems like there's an issue with your PyQt installation. I'd suggest going Conda (<a href="https://www.continuum.io/downloads" rel="nofollow">Anaconda</a> distribution), as it works out of the box (at least on Windows).</p>

<pre><code>conda config --add channels conda-forge
conda install orange3
</code></pre>

python data-mining orange
