After leaving the annotation session in Prodigy without saving through Jupyter Notebook, I sometimes struggle to upload a new set of data unless I completely switch the computer off and restart. In other circumstances, the uploading of new data requires just the closing the Anaconda session. Basically, the problem is that the web server/localhost is already occupied by the previous set of documents. How can I easily kill the processes and start a brand new session?
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:
