Documentation Problem/Question/Comment

Following the documentation it should be possible to start an interactive ipython shell on the head node.

# From your local machine.
$ kubectl -n ray exec -it ray-head-5455bb66c9-7l6xj -- ipython

However, when I tried this, ipython seemed to be not installed and I first had to install it using pip.
I can add ipython as a dependency to the autoscaler container if desired.
