The Main Problem is that once a prodigy session is started i dont seem to be able to terminate it anymore.
So it isnt possible to start another prodigy process with e.g. a different dataset unless i terminate the sessions kernel of the jupyterlab session.

I think this comes down to how Jupyter / JupyterLab handles a server that's started in a cell and how it lets you terminate it. This thread has some approaches that might be more convenient than restarting the whole kernel:

Stopping the Prodigy server in a Jupyter Notebook

When you run Prodigy, it starts a regular web server on the given host and port. So you'll need to terminate the web server – otherwise, it keeps running on the port. (This isn't specific to Prodigy btw and you'll be able to stop the Prodigy server just like you'd stop any other server in your notebook). I think Jupyter Notebooks just let you press the "stop" icon on the cell? Also see this Stack Overflow thread:
