I am not able to reproduce this issue with a clean virtual environment either as a python file executing or inside a notebook. It seems like your environment where this...

It matters more how you built the dependency chain for that environment in the docker container than the final state of it missing a dependency. With a fresh `python -m...

So one of the issues is captured here https://github.com/jupyter/nbclient/issues/48 -- there's already a PR for that https://github.com/ipython/ipython/pull/12301 to fix the lack of an error response. If you're in a notebook...

Open to PRs for improving the descriptions in the /docs directory as well :)

No there's not an option for that today. You'd have to extend and modify https://github.com/nteract/papermill/blob/master/papermill/clientwrap.py#L36, then [register it as a new engine](https://papermill.readthedocs.io/en/latest/extending-entry-points.html#developing-a-new-engine). Papermill has some stronger opinions than the underlying...

Sorry for the delayed response. So the issue is that the notebook is outputting javascript in the plot and for security reasons the classic notebook does not render javascript imported...

I agree we should do some message cleanup for tests. I'm not sure about the first one. I don't see it with virtualenv, so maybe a conda setup item? The...

For those message we mostly we need to suppress what we're testing for from reaching the console. Might need some tinkering with our mocks to get right.

Generally since we are processing JSON / YAML payloads and JSON does not support integer key indexes (https://stackoverflow.com/questions/8758715/using-number-as-index-json). It also complicates translating to typed systems if the keys aren't all...
