How can I troubleshoot issues with the Dask dashboard?

I'm having trouble with the Dask dashboard not displaying any tasks. What should I do?

First, ensure that your Dask scheduler is running. You can check this by running dask-scheduler in your terminal.

The scheduler is running, but I still don't see any tasks. What else could be wrong?

Check if your Dask client is connected to the scheduler. You can do this by running client = Client('your-scheduler-address').

I connected the client, but the dashboard is still empty. Any other suggestions?

Make sure that your tasks are actually being submitted. You can verify this by checking the logs for any errors or by using client.submit() to run a simple task.
