<h3>Objectives and design choices for the lecture notes<a class="headerlink" href="#objectives-and-design-choices-for-the-lecture-notes" title="Permalink to this headline">¶</a></h3>
<p>Contributors should keep the following objectives and design choices of
the SciPy lecture notes in mind.</p>
<p>Objectives:</p>
<ul class="simple">
<li>Provide a self-contained introduction to Python and its primary computational
packages, the ”SciPy stack“.</li>
<li>Provide tutorials for a selection of widely-used and stable computational
libraries.
Currently, we cover pandas, statmodels, seaborn, scikit-image,
scikit-learn, sympy, and mayavi.</li>
<li>Automated testing is applied to the code examples as much as possible.</li>
</ul>
<p>Design choices:</p>
<ul class="simple">
<li>Each chapter should provide a useful basis for a 1‒2 h tutorial.</li>
<li>The code should be readable.</li>
<li>An idomatic style should be followed, e.g. <code class="docutils literal notranslate"><span class="pre">import</span> <span class="pre">numpy</span> <span class="pre">as</span> <span class="pre">np</span></code>,
preference for array operations, PEP8 coding conventions.</li>

<p>with the value listed on <a class="reference external" href="https://repo.continuum.io/miniconda/">https://repo.continuum.io/miniconda/</a> . Miniconda can
now be installed:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">bash</span> <span class="n">miniconda</span><span class="o">.</span><span class="n">sh</span>
<div class="newline"></div></pre></div>
</div>
<p>Review the license agreement and choose a target directory (here we assume it
to be <code class="docutils literal notranslate"><span class="pre">$HOME/miniconda3</span></code>). Unless you intend to work more extensively with
miniconda, you do not want to modify <code class="docutils literal notranslate"><span class="pre">.bashrc</span></code>. In this case, you need:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>export PATH=$HOME/miniconda3/bin:$PATH
<div class="newline"></div></pre></div>
</div>
<p>to find the correct binaries. Note that the path depends on the target directory
chosen above.</p>
<p>Now, we use <code class="docutils literal notranslate"><span class="pre">environment.yml</span></code> from the main directory of the <code class="docutils literal notranslate"><span class="pre">scipy-lecture-notes</span></code>
repository to install the required dependencies. Note that <code class="docutils literal notranslate"><span class="pre">environment.yml</span></code> yields
an environment named <code class="docutils literal notranslate"><span class="pre">testenv</span></code>. If you prefer a more telling name, make a copy of
<code class="docutils literal notranslate"><span class="pre">environment.yml</span></code>, replace <code class="docutils literal notranslate"><span class="pre">testenv</span></code> in line 4 by a more appropriate name and use
this name in the following instead of <code class="docutils literal notranslate"><span class="pre">testenv</span></code>. The conda environment is created
by:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">conda</span> <span class="n">env</span> <span class="n">create</span> <span class="o">-</span><span class="n">f</span> <span class="n">environment</span><span class="o">.</span><span class="n">yml</span>
<div class="newline"></div></pre></div>
</div>
<p>Now, the environment can be activated:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">source</span> <span class="n">activate</span> <span class="n">testenv</span>
<div class="newline"></div></pre></div>
</div>
<p>and deactivated:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">source</span> <span class="n">deactivate</span>
<div class="newline"></div></pre></div>
</div>
<p>With an activated environment, you are now able to produce the html version of the
SciPy as explained above. Generating a pdf version requires the system packages
<code class="docutils literal notranslate"><span class="pre">texlive</span></code>, <code class="docutils literal notranslate"><span class="pre">texlive-latex-extra</span></code>, <code class="docutils literal notranslate"><span class="pre">texlive-fonts-extra</span></code>, and <code class="docutils literal notranslate"><span class="pre">latexmk</span></code>.</p>

<p class="topic-title"><strong>Installing the Python packages with pip</strong></p>
<p><a class="reference external" href="https://pip.pypa.io/">pip</a> is the recommended tool to install Python
packages. However, a number of packages must be installed from the system. Install
Python, the Python “headers” (the <cite>python3-dev</cite> package on Debian, for instance), a C
development environment, <a class="reference external" href="https://www.gnu.org/software/make/">GNU Make</a>, a full LaTeX
distribution (e.g. <a class="reference external" href="https://www.tug.org/texlive/">TeX Live</a> with extra fonts and
utilities) and <a class="reference external" href="https://git-scm.com/">git</a>.</p>
<p>The remaining software can be installed with <cite>pip</cite>. Depending on the configuration, the
probably most convenient and safe way to proceed is with:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">pip</span> <span class="n">install</span> <span class="o">--</span><span class="n">user</span> <span class="o">-</span><span class="n">r</span> <span class="n">requirements</span><span class="o">.</span><span class="n">txt</span>
<div class="newline"></div></pre></div>
</div>
<p>This will install the software in a local directory belonging to the user and will not
interfere with system-wide Python packages.</p>
