+  For upload the upload script has to be opened (can be in every environment). The name of the model file has to be

+
+<h4 class="space-above">Adding new model scripts</h4>

+<p>
+  Open Spyder in the base environment and open the model.py within.

+  <li>Enter model file name without .pkl in fetchData</li>
+  <li>Add new prediction function below others</li>
+  <li>duplicate another @app.route and rename according to desired route name and prediction function name</li>
+</ul>
+
+<h4 class="space-above">Testing locally</h4>
+
+<p>
+  To test the model Python script locally, you need to execute it in the base environment, in which all necessary
+  packages  have to be installed. Note that Spyder also has to be opened in the base environment.
+</p>
+
+<ul>
+  <li>Open a separate Anaconda Prompt and cd into the definma-UI folder</li>
+  <li>Adapt the model-mock.json at definma-UI/assets/ and enter the new model URL and name</li>
+  <li>Execute &quot;python -m http.server&quot; in the Anaconda Prompt</li>
+  <li>Execute the model.py script in Spyder</li>
+  <li>Navigate to <a href="http://localhost:8000">http://localhost:8000</a> in the browser</li>
+  <li>If there are problems with cached data, open the Browser developer console (Ctrl+Shift+I) and tick
+    &quot;Disable cache&quot; in the Network tab. The console then has to stay open.</li>
