Jinja can't find template path
<p>I can't get Jinja2 to read my template file.</p>

<p><code>jinja2.exceptions.TemplateNotFound: template.html</code></p>

<blockquote>
  <p>The simplest way to configure Jinja2 to load templates for your
  application looks roughly like this:</p>
  
  <p>from jinja2 import Environment, PackageLoader env =
  Environment(loader=PackageLoader('yourapplication', 'templates')) This
  will create a template environment with the default settings and a
  loader that looks up the templates in the templates folder inside the
  yourapplication python package. Different loaders are available and
  you can also write your own if you want to load templates from a
  database or other resources.</p>
  
  <p>To load a template from this environment you just have to call the
  get_template() method which then returns the loaded Template:</p>
  
  <p>template = env.get_template('mytemplate.html')</p>
</blockquote>

<pre><code>env = Environment(loader=FileSystemLoader('frontdesk', 'templates'))
template = env.get_template('template.html')
</code></pre>

<p>My tree ( I have activated the venv @frontdesk )</p>

<pre><code>.
├── classes.py
├── labels.txt
├── payments.py
├── templates
├── test.py
└── venv
