During execution of a cell "RuntimeException: The python kernel is unresponsive."

Valon98 — Tue, 10 May 2022 15:33:44 GMT

Hi all, I am running a preprocessing to create my trainset and test set. Does anyone know why during the execution my cell gives the error "RuntimeException: The python kernel is unresponsive." ? How can I solve it?

@Valerio Goretti , It's hard to know exactly why that would occur. One thing that works for me when I get strange errors is refreshing the browser. Sometimes the HTML doesn't render correctly. When that doesn't work, I try to disconnect and reattach my cluster. Once every few months, I need to restart my cluster and that always fixes things.

@Joseph Kambourakis Thank you for your reply. I use Databricks Community Edition so I restart the cluster every time it expires. I tried updating my browser but it keeps giving me the same problem...

@Valerio Goretti we need to look at the thread dumps to understand this issue. if the repl thread running the command is blocked by the partial result fetcher thread and If this is consistent with several threads dump snapshots, it suggests that the command is streaming a lot of stuff to the result buffer, so that the partial result fetcher can take more time than normal to send them to the tree store and frontend.
