Re: ipython interpreter prerequisites
I see this message when I tried to list all installed modules. I assume the IPython.kernel module got brought in by the "pip install jupyter". It seems I can replace it with "pip install jupyter_client"? The `IPython.kernel` package has been deprecated since IPython 4.0.You should import from ipykernel or jupyter_client instead.

Re: ipython interpreter prerequisites
Hi Question about the ipython interpreter prerequisites. The jupyter module version ( https://pypi.org/project/jupyter/) is pretty old. Can it be replaced by ipykernel module (https://pypi.org/project/ipykernel/)? Prerequisites - Jupyter `pip install jupyter` - grpcio `pip install grpcio` - protobuf `pip install protobuf` Will this work instead?- ipykernel `pip install ipykernel` - grpcio `pip install grpcio` - protobuf `pip install protobuf` Thanks Denny
Re: [GitHub] [zeppelin] zjffdu opened a new pull request #4193: [ZEPPELIN-5473] Enable z.show for R
Can you add a logic to check if the max result size is reached? If so, print
out a warning message. Essentially, the same behavior as found in the python
interpreter.
if exceed_limit: print("\n%html Results are
limited by {}.".format(self.max_result))

Re: z.show for R
We are using Zeppelin on the Oracle Autonomous Database Cloud for machine learning (OML). Currently, we enabled the OML4Py (Python language) in the notebook. We are working on enabling the OML4R (R language). It would be good to support common features (e.g. z.show) for both languages for better user experience.

z.show for R
Hi In R, we want to leverage the Zeppelin's built in visualization, but not sure how it will work. In python, we use z.show to display a data frame and leverage the built in visualization. Is there an equivalent for R? Moreover, the table display system (%table) doesn't seem to work in R. Thanks Denny

Re: Remote Interpreter
Thanks for the quick reply.
In our use case, we only use the python and db interpreters (no yarn, spark,
etc). We would start the Zeppelin server in one node (as a container).
Whenever, user runs a notebook, we would spawn a remote interpreter container
(in the same node). We use the isolated mode (one remote interpreter per
note). If we run out of resources in the current node, we would like to spawn
new remote interpreters in a different node (we manage all nodes ourselves).
We are using the DockerInterpreterLauncher to launch the remote interpreter
container.
I have a question about this script (used to start the interpreter inside the
container). I see the script accepts the zeppelin.server.rpc.host, which
allows the interpreter to communicate back to the zeppelin server. If I start
the interpreter in a different node, how does it tell the zeppelin server to
connect to that node? Please advise.
{{CONTAINER_ZEPPELIN_HOME}}/bin/interpreter.sh -d
{{CONTAINER_ZEPPELIN_HOME}}/interpreter/{{zeppelin.interpreter.group.name}} -r
{{zeppelin.interpreter.rpc.portRange}} -c {{zeppelin.server.rpc.host}} -p
{{zeppelin.server.rpc.portRange}} -i {{zeppelin.interpreter.group.id}} -l

Re: Python interpreter
Hi Currently, we are using Zep 0.8.1 and the python docker interpreter. Each user runs his notebook in his own docker python container. If user wants to install 3rd party modules (pip install) on demand, it doesn’t seem to work. How to install 3rd party modules via pip in the python container on demand? I see py4j running inside the container and there is a loop constantly looking for python script to execute. If user enters pip install in the paragraph to install 3rd party module, it doesn't work. Because it is not a python code. We need to use the container to run user script for security reason. On the other hand, it is highly desirable to allow 3rd party modules via pip install. Any suggestion? Thanks Denny

I see in the interpreter.json, each interpreter has an id associated. Is this
id used in anyway? Does Zeppelin use the name and group attributes only to
figure out the interpreter to use for each paragraph? When does Zeppelin
figure out interpreter to use? Each time when a paragraph is about to run?

Re: Question about interpreters
If I export a notebook from one Zeppelin instance and import it to a different
instance. There are possibilities that the new instance may have different
interpreter settings, so the interpreter ids may be different. How does
Zeppelin resolve the id differences? The interpreter ids seem embedded in the
notebook json data. If any of these ids don't match the interpreters in the
new instance, what would happen?
"angularObjects": { "2BDFTKHGQ": [], "2BB471VK2": [],
"2BCJUYDVX": [], "2BC45AGQM": [], "2BCGRMV7H": [], "2BDGM8X1N":
[], "2BC7KXZAS": [], "2BENDU4PZ": [], "2BD552SA5": [],
