It appears you are using PyCharm to run your code. If you prefer an interactive session, I would recommend that you utilize the "Python Console" to input your commands. This will maintain the session open so that you can access the Flow GUI from your browser, while maintaining your ability to inject your Python dataframes into the java server.

As an aside, I found difficulty importing csv files using Flow, but Python dataframes could be used to pipe the data into the process without error.
