<p>I follow instruction and run ipython.exe notebook:</p>

<p>Now if I run jupyter notebook, I get:</p>

<blockquote>
  <p>C:\Miniconda3\Scripts>jupyter notebook Traceback (most recent call
  last):   File "C:\Miniconda3\Scripts\jupyter-script.py", line 5, in

<p>I need to save my work as ipython notebook. How can I do it?</p>

<p>Like <code>zwol</code> said, your installation might have gotten screwed up.  There are two things you can do.</p>

<ol>
<li>Completely remove your miniconda installation and try again.</li>
<li><p>Create a new environment and install ipython/jupyter there.  I would try this first.  </p>

<p><code>conda create -n myenv python=3<br>
activate myenv<br>
conda install jupyter<br>
jupyter notebook</code>  </p></li>
</ol>
