ImportError: IPython version 6 is not supported.

Hello, when I pushed the "Deploy to Heroku" button and set a password, I got an Application Error after everything was done building. Here are the logs:

No way to install other python packages without forking?

Saving file problems

The issue is used to collect infos about problems with saving files to postgres. This includes working and non-working configurations.

Is it possible to add widget functionality?

Do you think it would be possible to add the notebook widget tab and support html exports?

Easy Deploy to heroku not working

Hi,

I've been trying to deploy to heroku using the heroku button.
Unfortunately, Heroku seems to get stuck configuring the environment.

Connection Issues

Whenever I upload a notebook, as soon as it starts running, it encounters connection issues:

I cannot reproduce the issue when running locally (using heroku local). On Heroku, this problem repeats and does not allow the execution of any code. Any hints as to what may be causing the issue?

How to use Python v2?

Hello, how can I add Python v2.x to the Jupiter Notebook Heroku Instance? I've tried adding a conda_runtime.txt file with the contents reading, Miniconda2-latest-Linux-x86_64.sh but it still seems to use Python v3.

notebook package not found

I'm getting this error in my heroku dashboard after forking and clicking deploy.

ResolvePackageNotFound: 
  - notebook=4
 !     Push rejected, failed to compile Python app.
 !     Push failed

Jupyter NB is not working with CloudFoundry

I'm not too familiar with CloudFoundry, but from what I understand, the change to Diego changed the way WebSockets work and possibly breaking this implementation of Jupyter. More relevant info in this IPython ticket: ipython/ipython#7178 (comment)

I'll submit a fix for it to get it working with the version of CloudFoundry (Pivotal Cloud Foundry 1.6.3-build.14) we're running. I'm not sure how it affects other versions, however.

Saving files (directory not in tree)

I'm saving a file on jupyter (deployed on heroku).

I cannot see the saved file in the local working tree.

However, the program is able to read the file.

This is odd. I'd like to be able to see the files I save and download them locally.

Any help is appreciated.

psycopg2.ProgrammingError: relation "pgcontents.users" does not exist

Installed on Heroku. Apparently an error when accessing DB. Please see the full log

Adding JavaScript support

How would I extend your app to include javascript (ijavascript) support? I would like the notebooks to include both python and javascript language support.

Thanks in advance

Notebook List Empty

Hello. I am interested in using this for a project I work for.

I forked the repository and entered some notebooks in the notebooks folder. Unfortunately, when I hit the deploy button, they don't show up. Instead I get a message reading 'Notebook List Empty' in the Jupyter home page.

Am I misunderstanding what this is?

Issues while deploying on heroku

Hi, I was using the click to deploy button below and it gave this error

-----> Installing Dependencies using /tmp/build_56938d30a27dd84cca915e0c8f940181/environments/default.yml

Size problem trying to use the numpy module

Unfortunately,
using heroku service, the scientific python modules are too large for deployment.

In the following "failed build" I tried to include numpy in environment.yml:

How to use IPython-notebook-extensions

Hi.

Your heroku-jupyter is great!!. I love it.

However, I would like to use IPython-notebook-extensions on the heroku-jupyter.
ipython-contrib/IPython-notebook-extensions: Some extensions for Jupyter notebook

I think it makes heroku-jupyter better.
So, could you please add description about how to use IPython-notebook-extensions in README.md?

Thanks you.
Atsushi
