Databricks Attribute Error: 'IPythonShell' object has no attribute 'kernel'

abi-tosh

I have been getting this error repeatedly when trying to run a notebook. I have tried attaching multiple different clusters and installing some of the libraries that it wanted me to update. I have also tried to clear the state of the notebook and restarted the clusters, but couldn't get rid of the error. Any tips to solve this?

I found this link:https://github.com/ipython/ipython/issues/10377.

Can you check if this is helpful?

@Lakshay Goel​ I ran into the same issue as abi-tosh and I don't think I am running any unit tests. The thing that trips me up about this is that we had this working in other jobs and it is failing for us now. It fails for us on

from great_expectations.core import (

ExpectationValidationResult,

ExpectationSuiteValidationResult,

)

I have bugged several people at my company and we are unsure how to tackle this. Please help.

Here is the error I am getting. Very similar every time

Found it, great expectations released a new feature that put us in dependency hell. 0.16.3 makes life difficult for some people.
