i got the same error as above (also working under windows 10 in jupyterlab).
Installing murmurhash does not show any effect.
I also changed the port for the prodigy localhost to e.g. 8081.
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.
Starting and Terminating Sessions from the console works fine however.
