Also this question I asked at stack overflow but no answer either. Sorry again for cross posting:
I am writing a new custom kernel for Jupiter Lab for our in-house programming language. If the compiler is not present I want to announce to Jupyter Lab that the initialization has failed. Ideally with a message how to fix the issue. Which messaging system should I use for that? -- You received this message because you are subscribed to the Google Groups "Project Jupyter" group.
