<pre><code>pip install -U scikit-learn
pip3 install sklearn
</code></pre>

<p>to install it; but when i type </p>

<pre><code>$ Python
&gt;&gt;&gt; import sklearn
</code></pre>

<p>it returns </p>

<pre><code>ImportError: No module named sklearn
</code></pre>

<p>I followed other tutorials, but it doesn't work. Furthermore, my enviroment returns this warning:</p>

<blockquote>
  <p>If you have installed scikit-learn from source, please do not forget
  to build the package before using it: run <code>python setup.py install</code> or
  <code>make</code> in the source directory.</p>
