 ## Check if you are ready
 
+[Versions of Python Compatible with MATLAB Products by Release](https://de.mathworks.com/support/requirements/python-compatibility.html)
+
+You need to ask yourself or better Matlab if it is using the correct Python. You can check this via:
+
+```matlab
+>> pyenv
+
+ans = 
+
+  PythonEnvironment with properties:
+
+          Version: "3.11"
+       Executable: "/data_1/davrot/P3.11/bin/python3"
+          Library: "libpython3.11.so.1.0"
+             Home: "/data_1/davrot/P3.11"
+           Status: NotLoaded
+    ExecutionMode: InProcess
+
+```
+
+If this is wrong (which it isn't in my case) then you can change it (temporarily?) with
+
+```matlab
+>> pyenv('Version','/data_1/davrot/P3.11/bin/python3')
+
+ans = 
+
+  PythonEnvironment with properties:
+
+          Version: "3.11"
+       Executable: "/data_1/davrot/P3.11/bin/python3"
+          Library: "libpython3.11.so.1.0"
+             Home: "/data_1/davrot/P3.11"
+           Status: NotLoaded
+    ExecutionMode: InProcess
+```
+
+**Obviously you need to use your location for your Python installation.**
